Adobe Interview | Set 1

Following are the details of Adobe Interview.

Round 1 1. How will you implement a stack using a priority queue. Push and pop should be in O(1). 2. Three mislabeled jars problem. Round 2 1. How does stack look in function calls? Given a recursive function call, how will the stack look like? 2. When does stack (process stack) overflow? What are the remedies? 3. What are balanced BSTs. Then he randomly gave me various numbers and asked me to create a BST. And to balance it. 4. Advantages of linked list over arrays. And arrays over linked list. 5. How are vectors implemented internally in the library. This question revolved around dynamic implementation of arrays. Then discussed the amortized time of the operations using dynamic implementation of arrays. Round 3 1. There was a question in written round that there is a global static variable ‘lock’ initially set to 0 and there was a code segment given. while(lock); lock = 1; //Critical section lock = 0; Does this solve critical section problem. I answered that it will solve in uni processor system but not in multiprocessor system. Then he asked me to explain my answer. After a long discussion we came to a conclusion that this wont even solve in uni processor system. Then he asked me the solution to solve this. I did that using testandset instruction. 2. When a function is called in thread, what variables can be accessed from it. There was a long discussion on this too. I went in the wrong direction but corrected myself later. Stack variables are copied but heap variables are same. Round 4 1. What data structures will you use to implement a text editor. Size of editor can be changed and you also need to save the styling information for all the text like italic, bold etc. Round 5 HR Round: Normal HR questions.

Adobe Interview | Set 2

I have recently been through the recruitment process of ADOBE. I didn’t get through (I got the reply today), but I sincerely hope that my experience will help some of you in your endeavors. Round 0: Written Test - I was called for a written test. The test was 3 hours long. It had four sections – Quantitative, Analytic, Data Structures and Algorithms, and Core Java & J2EE fundamentals The questions were simple. The paper had a time limit for each of the individual sections but somehow the HR collected the answer sheets (and the question papers) all together at the end of 3 hours. There was no negative marking but they had a different weight-age for questions in each section Quantitative: 30 multiple choice questions. Time limit: 45 minutes Analytical: 3-4 Analytical Puzzles followed by 4-5 follow up questions (multiple choice). Time limit: 15 minutes Data Structures & Algorithm: 10 questions (not multiple choice) to be answered with a brief explanation. Questions like 24ABC in base 6 would be what in a base 7 system. Write a program to find the missing number in an array of size N-1 which had jumbled up numbers ranging from 1 to N. I hope you get the idea. Core JAVA & J2EE – The Core JAVA section had general questions on JAVA. They stressed a lot on threads. I dint know much about J2EE but the whole paper had just 6 questions on it, so missing them didn’t cost me much. Almost a week later the HR informed me that I had done really well in the test and that I have to come to the ADOBE office for the first set of interviews. Interview 1 1) He gave me a custom PERSON object. This object had some properties like name, surname, age etc. He asked me to write a function which can return the size of this object. He asked me to write a generic code that will work with any object. The object may have inbuilt data types like in the PERSON object or it may have another custom object inside it such as a FAMILYBACKGROUND object. He gave me a few functions from the JAVA API which can tell you about the contents of an object. He asked me to write a helper function that can return the size of default data types like int, float etc. 2)

He gave me a sorted but rotated array and asked me to find the pivot.

Interview 2 1) He gave me a sorted but rotated array and asked me to search an element inside it without finding the pivot. Complexity of the solution should still remain O(Log n) 2)

Find the mean and median of the elements which are dynamically added at runtime.

3) I have a list of N teams T1, T2, T3 … Tn. Each of these teams has played a match against every other team. I have a function displayResult(Team T1, Team T2), it returns the team which won the match between any two given teams T1 and T2.

I have to write the teams in an order such the (n-1)th team (in the order) had lost to the nth team which in turn had lost to (n+1)th team.. For example if in a particular order, the teams appeared as T1, T2, T3, T4 … then team T1 had lost to T2, T2 had lost to T3, and T3 had lost to T4… It may be possible that T3 lost to T1 .. but that need not be taken into consideration while writing the order. Only the neighboring elements should be such that the element on the left has lost to the element on the right. How will you write the teams in this order? Write a code for it Make all the necessary assumptions you need to solve the problem. 4) Print an order of all the knight moves such that it fills up an 8 by 8 chess board. The moves should be such that no block that has been stepped on is visited again. After a few days, the HR informs me that I have qualified for the next round. Only this time my interview will be taken by some of the senior executives at ADOBE. Interview 3 1) General discussion about the work done in projects, internships etc. 2)

What is reflection? How does JVM find the right class to instantiate an object?

3) Draw a Pascal triangle. Write a code to print the elements of an N level Pascal triangle using a 1 dimensional array. Interview 4 1) Generate all possible combinations (of r elements) inside an array of size N E.g. arr [] = {2,8,14} All possible combinations of r=2 will be {2,8}, {8,14}, {14,2} 2)

Why are string objects immutable in java? How are Strings structurally designed in java?

3)

When should one use merge sort and when should one use quick sort?

HR General questions like if selected which office would I like to work for? Where do I see myself 5 years from now? etc etc… I stumbled on the interview questions in the fourth round (Probably why I wasn’t selected). Please post if someone has answers to them. Best of luck.

Adobe Interview | Set 4

Date Of Interview: 3rd December 2012

No. of Rounds: 1 Written exam + 4 rounds of PI Type of Interview: Campus Interview for freshers

Written Round The written round consisted of three sections 45 min each. The first was an objective type which consisted of 30 MCQs on basic Mathematical and Logical problems. Then there were 2 subjective papers each consisting of 10 questions. One was based on C programming and the other on basic engineering concepts. Interview Round 1 Model a datastructure for a DFA that takes an event as parameter and performs a desired action. Write a code that efficiently counts the total Set Bits in a number. Write a code that efficiently calculates X power n where x and n are integers. Write a code that efficiently calculates the nth term of Fibonacci series (He wanted a logn solution). Interview Round 2 What is Synchronization? What is Mutex? Reader Writer Problem There are 25 horses and a track which can race 5 horses at a time. Find the top 5 horses in minimum number of races. Assuming best horse always wins. Write a function to check if a singly linked list is a palindrome. Interview Round 3 What do you know about Volatile keyword explain with an example code. Declare an array of function pointers that return a pointer to a func that in turn return a pointer to a char array. Given a Roman notation of a number convert it into its decimal number. Write a function to do this. Given a string, find the length of the longest substring with distinct characters. What is Paging and why is it used? Interview Round 4 HR Round: Normal HR questions HIRED!! :D

Adobe Interview | Set 5

1st Round(Written Test) Consists of three sections with each section 1 hour to solve. Hence the written round was for 3 hours. I really liked the written round since it consists of everything starting from writing code(LCA, GCD, Middle of Linked list), Number conversion, Reduction of Boolean functions, Prefix to Infix Expression and evaluation of expression algorithm and finally aptitude. The written round consists of more or less everything one could imagine and it is far better than other companies like Amazon or Microsoft. But of course, Adobe does repeat questions . Adobe’s Interview Process was very good since in this month, I had given interviews of Amazon, Samsung, GoldMan Sachs and Fab which I have already shared with GeeksForGeeks. What I Like about their interview was their way of perception, they were judging people based on thoughts and not just bookish answer. In fact, one of the interviewer was rejecting people if you give a book answer. 2nd Round(Technical Round) a) Heavy discussion on Merge Sort, Amortized Analysis of Heap Sort – Made me solve recursion etc b) Made me write the complete code for dictionary of words(Trie data structure) 3rd Round(With Director) This interview had only one question and it went on for atleast 1 hour. It was a OOPS Design question a) Serialize and deserialize the object in an optimized way( I gave him the idea of Spill overflow etc). I actually took a deep dive by optimizing in bit level) . After the algorithm, he made me design a library such that if there are 100 clients to my lib, it should be maintainable and flexible. It was a subjective answer but since I have 2 years of Work ex in C++. I did give him a nice design. 4th Round(Tehnical) a) Design an LRU cache b) Write C program for tail command of Unix using dynamic behavior c) And then discussion started on my projects. It was again depth of C++ programming 5th Round(Puzzles) a) Only puzzles were there in this round. And all the puzzles could be found on net 6th Round(Technical) a) Implement a generic Object Oriented Stack a. Considering algorithm wise I explained him repeated doubling and linked list implementation.

b. Design wise, templatized the answer with heavy use of virtual functions to make the code generic and maintainable over a period of 2 years. Debate on what should Pop return when we templatize it ? b) Reverse a string word by word in place without using the swap function. The string in noteditable. This question was tricky as he kept building the question with constraints. But I really enjoyed it 7th Round(HR) Finally after many interviews I got through Adobe. I did have offers from other companies but Adobe was paying well. I thank Amazon for rejecting me else I wouldn’t have even sat for Adobe :P

Adobe Interview | Set 6 (On-campus for MTS-1)

I would like to thank the entire Geeksforgeeks team, whose contribution has helped me a lot in my preparation for the interviews and getting placed at Adobe. No of rounds: 1 apti + 1 written + 4 PI Aptitude Round: 1 hr 15 questions on Analytical Ability, 30 questions on Data Interpretation and Quantitative Ability Written Round: 2 hrs 10 questions on Algorithms and OS, 10 questions on output of C/C++ code snippets PI Rounds1st Round: 45 minutes 1. Implement a queue using 2 stacks( average time complexity O(1) for push and pop ) 2. Discussion regarding demand paging. Then the interviewer asked me to give a detailed implementation of demand paging, using object-oriented approach, considering everything from page tables to swap disk I/O to page replacement policies. 2nd Round: 45 minutes 1. This round started with a puzzle: There are two buckets- one having 100L water and another having 50L milk. A spoonful of water is taken from 1st bucket and added to 2nd bucket and the mixture is stirred, now a spoonful of the mixture is taken from the 2nd bucket and added to the 1st. Compare the final volume of milk in 1st bucket to the final volume of water in 2nd bucket. 2. Defective ball puzzle: Find defective ball among 7 balls using minimum no of measures. 3. A system sends multiple queries to find all primes between two given numbers. Provide service to each query in less than O(p) time(p is total no of primes) Solution: Perform Sieve of Eratosthenes initially and maintain list of primes. For incoming queries, use binary search to find first and last primes between given numbers. 4. A modification of Towers of Hanoi problem: Consider 3 towers A(source), B(auxiliary), C(destination) and n discs. All usual constraints of the original problem hold true, but a new constraint is added: No disc(s) can be moved directly from A to C or from C to A, B has to be used in between. Solution: For n discs and towers A,B,C as source, auxiliary and destination respectively, consider the following function: Move(n discs, A,B,C) { If(n==1) print(nth disc, A->B->C);

Else { Move(n-1 discs, A,B,C); print(nth disc, A->B); Move(n-1 discs, C,B,A); print(nth disc, B->C); Move(n-1 discs, A,B,C); } } It will take O(3^n) time instead O(2^n) as in the normal Towers of Hanoi problem. The interviewer seemed quite impressed with the solution. 3rd Round: 45 minutes 1. A robot can move forward either 1 or 2 steps. Find no of possible ways to reach nth step(easy DP problem). 2. Questions regarding scheduling concepts, how cpu burst length is predicted for SJF scheduling, exponential averaging, etc. 3. The interviewer asked me to implement my own timer service in the user-space. Using system timer countdown was not allowed, only reading current system time was allowed. Solution: Create a high-priority helper process P which will have some idea of flow of time(since we cannot use hardware timer) and hence will act as a sand clock for any process that requires timer service. P will have the following operations: t1=getSystemTime() do dummy op(which should take very less time) t2= getSystemTime() (t2-t1) will be the time unit for P. Whenever any process requires a countdown of time t, it will communicate with P and request it to send a signal after time t. P will divide t by its time unit and perform dummy its operation t/(t2-t1) times and then notify the requesting process that the time period has elapsed. The interviewer said that the solution was coarse, but still he seemed pleased with it. 4th Round(HR Round): 15 minutes

Normal HR questions like: why do you want to join Adobe, what were the most challenging situations you have faced in your career so far, where do you see yourself in 5 years, etc. After the final round, the results were declared. I along with 4 of my peers were hired!!!

Adobe Interview | Set 7 (On-campus for MTS-1)

First of all, I would like to sincerely thank the entire GeeksforGeeks team for creating and maintaining such an awesome site. GeeksforGeeks has tremendously helped me in my preparation for the on-campus interviews and finally cracking the job interview for Adobe. Type of Interview: On-Campus for MTS 1 No of rounds: 1 apti + 1 written + 4 PI Aptitude Round: 1 hour There were 15 questions on LR followed by 30 questions on DI. The questions were similar to those asked in management examinations like CAT. The results were declared after a couple of hours and around 50 odd students were selected for the written round. Written Round: 2 hours It was divided into two sections : Section 1 contained 10 questions including a couple of questions on OS and the rest were common programming questions. Section 2 had 10 syntactical questions on C/C++. I guess most of them can be found on GeeksQuiz. 15 students cleared the written test and were to attend the PIs the next day. PI Rounds1st Round: 45 minutes 1. Had a general discussion about various data structures. Comparison of BST and hashmap ( relative advantages and disadvantages ). Applications of each. 2. Implement a queue using 2 stacks. Then optimize the implementation. 3. Suppose we have two functions void g() and void h(). The function h() has been called somewhere in the body of g(). Now using a debugger, we find that that the program crashes as soon as the return statement in h() ( at the end of function h() ) is executed. There is nothing syntactically wrong with the program. How will you debug the code ??? My answer : The function h() has modified the return address on stack. 4. The last question was a puzzle. You have 7 coins out of which one is fake. Find the fake coin in minimum number of weightings. 2nd Round: 45 minutes 1. The round started with a rigorous discussion about various OS concepts, specially virtual memory and demand paging. 2. Implement a stack using 2 queues. Now optimize the implementation. 3. A robot can walk on 1 step or 2 steps. Find the number of ways in which he can reach the nth step. I started with the naïve recursive solution. He asked me to draw the entire recursion tree and hence manually find the answer for n=8. I asked him to make it n=5 :D I pointed out the overlapping subproblems and gave him the DP solution. He also asked for time and space complexities of both the solutions.

4. This question was related to what he called conditional operator on an image. I had no idea what that was. So he explained it to me. A monochromatic image is represented by a MxM matrix Image0. We have another WxW matrix Op ( W> and >>> O/P questions related to string.concat, equals methods. Error pointing codes with options F2F Round 1:(1.2 hr) 1) Brief intro about work. 2) Why do you want to shift when Mobile (and ecommerce) are already the most happening things. 3) Test cases for mail attachment(word doc) not being opened scenario 4) WAP to convert a binary to decimal.(i wrote by taking the parameter as String, he asked me to do by taking as int) 5) WAP to print sum of first ‘n’ prime numbers 6) String s = "Hello "; s+ = "Adobe ";

s.trim(); System.out.print(s); What is the output? 7) Explain a project you have been recently been part of and what are the test cases you have gone through. 8) What is the testing framework you have used in Android.What is the approach you follow while testing any product.How do you test a method which does not return any value. 9) What are the operating systems you have worked on.Do you know Unix. 10) What are the main things that you need to look at while making a mobile application to that of a desktop application 11) What is the toughest bug you have fixed. 12) What is memory leak 13) What is the difference between instance variable and local variable 14) If i write java in command prompt from anywhere in system, will it work?If not, how to make it work. 15) Why is the class name same as filename in Java.Is there any use. Can a file have more than two classes.What will be the name of that file? How many class files will be generated when we compile. 16) Why is Java platform independent. 17) Is JVM platform dependant?On what factors it depends? 18) What are the best practices you have followed in your project. He asked me if i have any questions.I asked more about the role and team. He explained in detail about the team and also about Adobe subscription model.We had a general discussion over this business decision. F2F Round 2:(30 min) 1) Brief intro 2) WAP to find out factorial of a number He asked for recursion as well. Asked me to write the testcases and handle the overflow condition and border cases in the code. Discussed which approach is better and when to use which. 3) Do you know Unix 4) Do you know any other mobile platform apart from Android. Do you know any application platform which enables building apps across channels (desktop,android,ios,cloud…) He asked me if i have heard about PhoneGap and later explained it. He asked me if i have any questions. I asked if they have a mobile team separately.He said yes and explained their work a bit. F2F Round 3:(1 hr) 1) Brief intro 2) What is binary search. 3) Write a code for ternary search. Is it better than Binary? He asked me to generalize the search and asked me which is the optimum. 4) What is registry. 5) Do you know Unix 6) I have a hard disk of 100 gb.It has one and only file of 80 GB (database backup). What happens if i delete it and it goes to recycle bin. Follow-up questions: Is the memory freed from the hard disk. What happens if i move it from one drive to another. What happens in case of permanent delete.

What happens when we format the disk. 7) What is virtual memory. 8) Puzzle:10 containers with 100 balls each but one container defective.Find out the defective container in minimum weighings. He asked me for questions. I asked them if there will be option to shift to developer position.He said yes and explained about their open culture.Also explained how they interact and work closely with developers. Director round:(40 min) 1) How was the day. 2) What is the most interesting question you have been posed today. 3) What is it that you have learnt today. 4) Give me a brief about your work. 5) Why do you want to shift from Development to Testing. He said he will concentrate on only problem solving, aptitude and attitude1) Gmail wants to provide a new enhanced service which offers auto-backup , promotional mails filtered,extra space for mail box etc which costs 50 rs per month. They want to run a provisioning program which shows a popup to certain customers having options1) Yes and then redirected to payment and all 2) Remind me after 2 weeks. 3) No 4) Not happy with the service offered. Asked me to test this model. Later he asked me the factors which i will consider for choosing set of customers for this program. 2) Have you worked on Unix. 3) What is registry. I have installed msword in my pc.Copied the C/program files/ folder into pen drive and pasted in another pc.Will it work? Why /Why not? 4) What is SaaS. Examples. There is one fb user in India and another in US.When they communicate, do they connect to same server. If not then how does the communication happen?What is the data that is being transferred. This round felt like a stress test and went very badly. Couldn’t ask for any good questions when he offered. :( (My suggestion will be , answer only if you know and you are sure about it otherwise dont even try)

Adobe Interview | Set 11 (On-Campus)

Adobe procedure consisted of two online rounds back to back.

1) First Online Round- It was Aptitude Test of about 50 minutes and 40-45 Questions were there. The questions were easy and everybody could easily solve that, speed should be good in order to attempt all the questions. The questions were of type- some geometry based questions,some easy puzzle type questions (like there are 5 painters, one painter passionate about scenic beauty, 2nd painter has interest in… , and other information was given and 3-4 related questions were there),some simple comparison based questions and some quantitative aptitude questions. 2) Second Online Round- It was of 2 hours. In this round there were about 10 coding questions and 10-12 simple c o/p(pointer related) and data structure related question. Coding Questions asked can be easily found in geeksforgeeks, some of the questions that I remember are1) Reversing a linklist.(trivial question which everybody should know). 2) Given a 2-D binary matrix(nxn)(elements are either 0 or 1) such that in each row,all the 1’s in the array are present before the 0’s.You have to return the row number of the row with max. no of 1’s.You just have to implement the function whose prototype looks likeInt max_row(int *arr,int n);//here arr is a pointer to integer and nxn is the size of matrix. 3) Write a program to check whether the number is palindrome or not. 4) A recursive program to multiply two numbers with addition such that there should be minimum no. of recursive calls. 5) Given an array of n integers, find pair of numbers if present whose sum is equal to a given target sum. 6) Every number with 3 at it’s unit place has a multiple which has all 1’s like for 3,the multiple is 111,for 13 multiple is 111111.The multiple can exceed the integer range i.e,it can be very large number(try storing it in a string). 7) Given a mathematical expression, check whether the parenthesis used in that expression are balanced or not.Possible parenthesis used can be {},[],() only.Eg.(2+3)/4*[9+{8*5}]. 8) Three processes p1, p2, p3, p4 – each have sizes 1GB, 1.2GB, 2GB, 1GB. And each processes is executed as a time sharing fashion. Will they be executed on an operating system. 9) One question was from scheduling in OS. Technical Interview 1 In this round,firstly the interviewer asked me about DNS server(full working), ARP protocol etc. We had some general talks regarding my achievements, then he gave me a problem- There is a string which may contain repeated words, you need to print unique words only.(I gave a solution using trie but he wanted brute force solution…:( ) Then he gave a puzzle which I had never heard before(you can search it- “King’s poisonous wine cellars”).

He was also asking approach for some of the questions asked in written exam. Technical Interview 2 In this round,first of all I was asked some networking questions,then virtual memory concepts,some scheduling questions etc. Then he gave me a problem which I had to implement in C.The problem goes like this- There is an application which is again and again fetching data from database and then using that information in further processing,but since the application is again and again accessing the same database so inorder to increase the speed of accessing data we have to implement a cache.(Property of cachekeep the most frequently used data and remove the least frequently used data if cache is full,assume limited size of cache). Solution that I first gave was using a linklist (wrote all functions inC) He was happy with the solution but wanted me to think about more efficient solution so I told him using Heap and Hashing,implemented it in C again.He was impressed by this solution …:) Technical Interview 3 In this round he asked me about DHCP,DNS working protocols etc.(I wrote these terms in my resume).He asked about unions,bitfields,structures,asked me to write 6-7 complicated declarations,asked me the meaning of some declarations(like int *const *const *i).Then asked C++ Questions about default functions in C++,how would you detect that error has occured inside the constructor and destructor,lots of c/c++ output questions.I was also asked about reimplicit cast etc. but since I never studied so I simply denied(If you don’t have any idea about something or heard the term for the first time,it’s better to simply tell that u don’t know that,rather than fooling around..). Output questions were easy if you have done 295C Questions and GeeksForGeeks C/C++ Output Questions. HR Interview My third technical and HR Round were scheduled on second day and after my third tech. round I got more confident which really counts in HR round.You should be really confident about each and everything you speak and kindly think before speaking something so that he may not be able to trap you. First of all he asked my iit rank and AIEEE rank, then why among all the options I chose this college, then tell some unique and different quality that you possess so that i should hire you(he warned me not to say words like honest, hard-working, determined etc., it should be something unique also think of a situation if u could fit in with that quality), why adobe?, what is my weakness and how will I overcome it, then he gave me a puzzle to solve. Also I forgot to add the most common question which you are asked if interviewing in adobe and you are not among the toppers, where do you stand(rank) in your class, what is the reason of your low pointers(prepare a genuine answer to this question). In the end all went well and in my favor and I got recruited for the company.

Adobe Interview | Set 12 (On Campus for MTS-1)

1. Online Technical Round (2 hrs) 7 coding problems were given along with 13 mcqs. Coding Problems were very easy.

2. Online Aptitude Round(50 minutes) 45 questions were there. Time was the only limit in this round. Two LR passages, 1 DI problem and rest were quant questions. 16 were selected after the online rounds. 3. Round 1 PI This round was all about concepts of C, C++, Compiler, Debugging, Design patterns a. Tell about different sorting algorithms and their complexities. Why so many sorting algorithms present where only one can serve the purpose. Advantages and disadvantages of quick sort and merge sort. b. What happens when a C program is compiled and executed in details. c. Where are local variables, dynamic allocated variables, global variables stored? d. Where are static variables stored? e.
