KVPY INTERVIEW
INTRODUCTION The main idea behind an interview is to determine the personal suitability of the candidate for a particular scholarship or job. It is the final challenge which the candidate has to face in order to get the admission, job or scholarship he / she seeks.
WHAT IS AN INTERVIEW ? Interview is employed as supplementary to the written examination and is an additional test at which the personal qualities of the candidate such as intelligence, habits, behavior and presence of mind are assessed. It is a face-to-face meeting, especially for the purpose of obtaining a statement or for assessing the qualities of a candidate. It further indicates a physical meeting of people with two possible objectives: •
To obtain a statement or opinion – as is done when the president is interviewed to get statement on the result of his discussion with other political leader or when a sportsperson is interviewed to get his views.
•
To assess a person for selection – such as interviews for admission to educational institution, for jobs, etc.
Many candidates who pass the written exam with credit are unable to impress the interviewers and are, therefore, rejected. The candidate should not get perturbed when the interviewer tries to screen him and play on his nerves. Brief, to the point, but clear expression is always likely to impress the members of the interview board.
PREPARATION FOR THE INTERVIEW You must remember “ Opportunity is bald-headed on the back side “. Therefore, you must be prepared to avail yourself of the opportunity as and when it comes your way. You cannot thumb your way down to the highway of life and arrive at any worthwhile destination. All your mental and intellectual resources should be mobilized to face the battle of interview with a measure of success. A candidate has to keep in mind the type of interview he has to face. Whatever be the type of interview, the candidate must possess certain qualities like politeness, cheerfulness, good manners and behaviorism.
ALWAYS REMEMBER
One of the most fundamental factors that contribute to the success of an interview is the time and quality of preparation made by you.
The degree of preparedness for an interview helps reduce the uncertainty and anxiety prior to the interview.
The amount of effort you wish to put into preparation is directly proportional to the importance of the interview.
SOME FUNDAMENTAL QUALITIES 1. Personality
2. Confidence
3. Alertness
5. Mannerism
6. Smartness.
7. Knowledge.

KVPY INTERVIEW - 1
THE INTERVIEW ROOM HINTS FOR THE CANDIDATES : 1.
The members of the interview board will be watching the candidate very carefully. Therefore, there should be nothing outward in the manner of his entering the room. Prior to entering the room, adjust the attire. There should be a natural smile on the face and his gait should be dignified.
2.
Enter the room neither very hurriedly nor very slowly. Normal pace and dignified entry must characterize the candidate’s appearance before the interview board.
3.
Do not enter the room with a bowed head or a tensed face.
4.
Before entering, enquire by saying ‘May I come in sir / madam?’.
5.
If the door was closed before you entered, make sure you shut the door behind you softly.
6.
Face the panel and confidently wish ‘Good day sir / madam’.
7.
If the members of the interview board want to shake hands, then offer a firm grip first maintaining eye contact and a smile.
8.
Seek permission to sit down. If the interviewers are standing, wait for them to sit down first before sitting.
9.
After taking your seat you should look pleasantly at the chairperson and wait patiently for him to speak.
10.
Do not stand up when you are asked to answer a question. You should reply the questions sitting calmly in your seat.
11.
You should not place your portfolio, containing your testimonials etc., on the table. Keep it down by your side.
12.
Keep your hands on your chair in a normal position and don’t keep them on the table.
13.
An alert interviewee would diffuse the tense situation with light-hearted humour and immediately set a rapport with the interviewers.( But don’t tell them a joke !).
14.
Speak in a soft but clear tone. Your words should be well chosen. They should convey your ideas clearly and unambiguously to the interviewers. Maintain a normal pitch and a normal speed.
15.
Your manner of leaving the room is also of great importance. Do not get up before you are asked to do so. When you are told “ that will do, Mr. …… “ you should get up from your seat without materially disturbing the position of your chair. You should politely thank the chairman, turn back and leave the room without looking back at the members while approaching the exit.
DO’S (a) Always remember that the interviewers are men of great experience. They are fully acquainted with the nature of the qualities and the duty required of a person. They can judge a person’s worth and his capabilities from his words and expressions. (b) Have sufficient confidence in yourself to evoke confidence in the interviewers. (c) Give the best to the interviewers. Cover your weaknesses through the presentation of other achievements. (d) Remain unperturbed and be a keen listener too. (e) Feel pleased with your surroundings and be at your ease in the company of the interviewers. (f) Be prompt without being hasty, quick without being aggressive. (g) Emit vivacity and enthusiasm from your looks and expressions. (h) Show pleasing and graceful manners, sufficient politeness and dynamism.

PREPARATION FOR THE BIG MOMENT
Accumulate the vital information about the Institute / Scholarship It is important to know the background of the institute you apply to. You must read its brochure and visit its website. It is important for the following reasons:
•
Selectors cannot comprehend why and how a person can say he is keen to join an institute about which he knows little or nothing.
•
From the interviewer’s point of view the good applicant is one who has done some homework about the institute.
Keynotes you must be aware of : (a) (b) (c) (d) (e)
A brief history of the institute /organization. The main features of the institute /organization . Location. Any important issue of the institute /organization that has been newsworthy. Key people in the institute / organization.
Refresh yourself on your subjects of schooling : (a) It is but natural that interviewers would quiz you on your favorite subject. (b) You may like to go back to the principal text books and refresh your knowledge definitions, formulas, concepts and other related issues. (c) An interviewer judges your ability to perform on future tasks on the basis of your past performance.
Thorough knowledge on claims made (a) You should list your achievements, academic qualifications and extra-curricular activities. (b) Such achievements or claims may be authenticated by certificates or photographs. (c) The important ones may be photocopied and attached with the resume while the originals of all certificates should be neatly catalogued in a folder and kept at hand for reference, as the interviewer would ask for them.

TIPS FOR THE INTERVIEW
Lead the interview • A good interviewee would be quick to settle and begin to lead the interviewers rather than being at the receiver’s end.
Enthusiasm • The interviewer normally pays more attention if you display enthusiasm in whatever you say.
•
Put forward your views and ideas energetically.
•
Maintain a cheerful disposition throughout the interview.
Be candid and brief • Brevity is the hallmark of a good communicator. •
It is recommended that you volunteer information, but this must be done in lucid and to-the-point manner.
•
An over-talkative or verbose interviewee is instantly disliked and misjudged.
Avoid bluffs •
If you do not know the answer to a question, it is better to acknowledge it, rather than trying to bluff your way through it.
•
The interviewer will respect your honesty.
•
In our experience, interviewers immediately take a stance of grilling a candidate if they suspect him or her of lying.
Humour • A little humour or wit thrown in the discussion occasionally enables the interviewer to look at the pleasant side of your personality. If it does not come naturally do not contrive it. •
By injecting humour in the situation doesn’t mean that you should keep telling jokes. It means to make a passing comment that, perhaps, makes the interviewer smile.
•
A little humour as a starter will ease the fatigued minds. However, if you do not have a knack for humour, it is better not to get into it.
•
Mostly interviews are conducted throughout the day leading to fatigued minds.
•
You must be proactive in offering information about yourself as the interviewers will be willing-listeners.
Be refined and well-mannered •
The way you conduct yourself reflects your upbringing and your culture.
•
It is good to project an air of humility
•
Over confidence is often misinterpreted by interviewers as arrogance.
•
Polite statements are recommended.
Do not use slang • During an interview, slang will probably not be understood, and certainly not appreciated. Your communication needs to be as formal and explicit as possible
Composure • Your posture during the interview adds to or diminishes your personality. •
The way of sitting tells a lot about the nature of the candidate.
•
Mannerisms such as playing with your tie, theatrical gesticulations, shaking legs or sitting with arms slung over back of adjoining chair must be avoided.
•
It is vital to be conscious of your posture and gesticulations as they tell a lot about your personality.
•
You should keep all certificates, testimonials and other relevant documents neatly on the table, preferably in a single file. Corporate Office : CG Tower, A-46 & 52, IPIA, Near City Mall, Jhalawar Road, Kota (Raj.)-324005

KVPY INTERVIEW - 4
Maintain Eye contact •
You must maintain eye contact with the panel, right through the interview. This shows your self-confidence and honesty.
•
Many interviewees while answering, tend to look away. This conveys you are concealing your own anxiety, fear and lack of confidence.
•
Maintaining an eye contact is a difficult process. As the circumstances in an interview are different, the value of eye contact is tremendous in making a personal impact.
Ask questions if necessary •
Many interviewees believe that an interview is a one-way street, the hapless ‘victim’ struggling to be selected and the ‘all powerful’ being in whose hands lies the destiny of the interviewee. It is a myth.
•
You may ask a question / clarify information if necessary. It is quite in order and much appreciated by interviewers.
Be a good listener •
It is imperative for you to listen carefully to the question being asked.
•
If a question is not clear, it would be quite in order for you to seek clarification on the same.
•
Seeking a clarification is far better than giving an irrelevant answer.
•
It is very annoying for interviewers when an interviewee misinterprets the questions, and answers by saying something which is irrelevant.
Be calm, polite and controlled •
Many interviewees adopt a stance which is not their natural self.
•
It is amusing for interviewers when a candidate launches into an accent which he or she cannot sustain consistently through the interview or adopt mannerisms that are inconsistent with his / her personality.
•
Interviewers appreciate a natural person rather than an actor.
•
It is best for you to talk in the natural manner because then you appear genuine
ARCH TYPE QUESTIONS Q.1
Q.2
Let us know about yourself •
This is a very general question in which you can say almost anything about yourself.
•
Prepare yourself for such a question so that you can tell about those thing which are important such as basic details, your personality traits, achievements, aspirations, motivations and ambitions.
•
Remember that a two-sentence answer will only convey how little there is to know about you.
•
You should be able to say a lot without being verbose or self-opinionated.
•
The answer should be such that it gives a definite direction to the interviewer and no further questions are asked on this.
What are your strengths and weaknesses ? •
This is a question that has stumped many an interviewee.
•
It is asked to ascertain how much you know about yourself, since a person who knows oneself well is likely to be more effective in life.
•
Many interviewees find it difficult to verbalize their strenghts and weaknesses.
•
The best way to tackle this question is to reply courteously. Mention your weaknesses tactfully. Corporate Office : CG Tower, A-46 & 52, IPIA, Near City Mall, Jhalawar Road, Kota (Raj.)-324005

Q.3
Let us know something about your family background. •
This question is asked by interviewers in order to determine the social, cultural, religious and economic milieu you have come from.
•
It gives the interviewer a clue about your attitude and values.
•
The best approach to such a question is to bring out not only the facts of parentage and background but also some of the good principles they have taught you. Mention family values.
•
In our experience, most interviewees simply mention their father’s name and occupation. They may sometimes tell about their brothers and sisters with special emphasis of those who may have done well in life.
Q.4
What are the perceived benefits you visualise from KVPY ? •
An interviewer generally asks this question to ascertain the candidate’s concepts / views about KVPY.
•
Interviewee must be aware of the importance of KVPY i.e. it enables candidates to be versatile in all the science subjects.
•
It also reduces the financial burden of the parents.
•
It instils confidence in the candidates and it increases the probability of being selected in any career based competitive examinations.
THE BOTTOMLINE Managing yourself effectively under all circumstances is critical to your success. Tell yourself that you are as much an architect of a good interview as the panel. You will enjoy the experience with this perspective. Success isn’t far away, the key is up in your mind. Unlock and walk into the world of success. Best of luck too!!
And Finally .................
BELIEVE IN YOURSELF ! He is an atheist who does not believe in himself. The old religions said that he was an atheist who did not believe in God. The new religion says that he is an atheist who does not believe in himself. Never think there is anything impossible for the soul. It is the greatest heresy to think so. If there is a sin, this is the only sin - to say that you are weak, or others are weak. Whatever you think, that you will be. If you think yourselves weak, weak you will be; if you think yourselves strong, strong you will be. ‘’Believe in yourself. The world will be at your feet’’ said Swami Vivekananda. Same belief is also required for you to succeed in GDs, Interviews etc.

KVPY Interview Questions YEAR : 2013 PART–I (PHYSICS) Niranjan Prasad 1. Sol.
What is Newtons First Law of Motion? Newton’s law from an 1803 translation from Latin as Newton wrote “Every body preserves in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed thereon”.
2. Sol.
What is the need of First Law of motion when Second Law of Motion is present? Isn't inertia implicit in the Second Law? First law define the frame of reference while Second law measured the force and in second law motion nothing is mention related to the frame of reference i.e. to apply second law of motion, first law must be known.

Write down the Faraday's law of electromagnetic induction? (i) When magnetic flux passing through a loop changes with time or magnetic lines of force are cut by a conducting wire then an emf is produced in the loop or in that wire. This emf is called induced emf. If the circuit is closed then the current will be called induced current. magnetic flux = B.ds
(ii) The magnitude of induced emf is equal to the rate of change of flux w.r.t. time in case of loop. In case of a wire it is equal to the rate at which magnetic lines of force are cut by a wire E=–

Why does electric monopole exist while magnetic monopole does not exist? Because magnetic dipole produce only due to current in a circular loops (due to revolution of electron around the nucleus). Magnetic lines of forces exists in a close loop only while electric lines of forces may be without a close loop. So magnetic monopole non exist.

PART–II (CHEMISTRY) JAHNVI PATEL 1. Sol.
Explain Bohr Theory model of Atom. BOHR’S ATOMIC MODEL Bohr’s model is applied only on one electron species like H, He+, Li++, Be+++ etc. The important postulates of Bohr model of an atom are (a) Electron revolves around the nucleus in a fixed circular orbit of definite energy. As long as the electron occupy a definite energy level, it does not radiate out energy i.e. it does not lose or gain energy. These orbits are called stationary orbits. (b) Electron revolves only in those orbits whose angular momentum (mvr) is an integral multiple of the factor h/2(where ‘h’ is Plank’s constant)
mvr =
h n 2
where : m = mass of the electron v = velocity of the electron n = number of orbit in which electron revolves i.e. n = 1, 2, 3 ........ r = radius of the orbit. (c) The energy is emitted or absorbed only when the electron jumps from one energy level to another. It may jump from higher energy level to a lower level by the emission of energy and jump from lower to higher energy level by absorption of energy. This amount of energy emitted or absorbed is given by the difference of the energies of the two energy levels concerned.

Characteristic of SN2 1. It is bimolecular, one step concerted process 2. It is second order reaction because in the rds both species are involved 3. Kinetics of the reaction
rate [substrate] [nucleophile] rate = k[substrate] [nucleophile]
If the concentration of substrate in the reaction mixture is doubled, the rate of the nucleophilic substitution reaction is doubled. If the concentration of nucleophile is doubled the rate of reaction is also doubled. If the concentration of both are doubled then the rate of the reaction quadriples. 4. Energetics of the reaction :
Figure : A free energy diagrams for SN2 reaction
5. No intermediates are formed in the SN2 reaction, the reaction proceeds through the formation of an unstable arrangment of atoms or group called transition state. 6. The stereochemistry of SN2 reactions As we seen earlier, in an SN2 mechanism the nucleophile attacks from the back side, that is from the side directly opposite to the leaving group. This mode of attack causes an inversion of configuration at the carbon atom that is the target of nucleophilic attack. This inversion is also known as Walden inversion. Inversion
7.
Factor's affecting the rate of SN2 reaction Number of factors affect the relative rate of SN2
reaction, the most important factors are (i) Effect of the structure of the substrate SN2 reactivity CH3 > 1° > 2° >> 3° (unreactive) The important reason behind this order of reactivity is a steric effect. Very large and bulky groups can often hinder the formation of the required transition state and crowding raises the energy of the transition state and slows down reaction.

(ii) Concentration and reactivity of the nucleophile As nucleophilicity of nucleophile increases rate of SN2 increases. Anionic nucleophiles mostly give SN2 reaction A stronger nucleophile attacks upon -carbon with faster rate than the rate of departing of leaving group. (iii) The nature of the leaving group Weaker bases are good leaving groups. A good leaving group always stabilise the transition state and lowers its free energy of activation and there by increases the rate of the reaction. Order of leaving ability of halide ion F¯ < Cl¯ < Br¯ < I¯ Reagents for alkyl halide are : OH¯ , SH¯ , I¯ ,CN¯, NH3 ....... (strong anionic nucleophile) 17.

21. Sol.
What is the difference between a bacterium and a virus? Bacteria are unicellular prokaryotic living organisms and viruses are nucleoprotein particles devoid of cellular organization and metabolism. Viruses are obligate intracellular parasites and hence are neither living nor dead. What is AIDS and which micro-organism causes it? The word AIDS stands for Acquired Immuno-Deficiency Syndrome. AIDS is caused by the Human Immunodeficiency Virus (HIV), a type of retrovirus.
22. Sol. 23. Sol.
Why a cure for AIDS hasn't been found yet and how does it affect our body? Due to high mutation rate of HIV, vaccination hasn’t been possible. It causes immunodeficiency due to destruction of CD4+ receptor cells or helper T cells.

What are the different types of extinctions? Extinction occurs when the last existing member of a given species dies. It is a scientific certainty when there are no surviving individuals are left to reproduce. Functional extinction occurs when only a handful of individuals are left, and the chances of reproduction are poor. Coextinction The loss of one species leads to the loss of another in a chain effect. A small impact in the beginning of an extinction can have an overall larger effect. Coextinction could be a result of a predator losing its food source or key species becoming extinct leading to the ecosystem becoming off balance. Mass extinction– It is also known as an extinction event that destroys many species at once. It is characterized by a sharp decrease in the number of species on earth in a short period of time. Planned extinction–Human controlled extinction were through to be helpful for the human population but generally ended in the spread of deadly viruses e.g. smallpox-extinct in the wild, polio-nearly extinct but can be found in some parts of the world.

What do you think about Lamarckism and list out a few examples to disprove Lamarckism from daily life?
Sol.
Lamarckism suggests that variations among organisms originate because of response to the needs of the environment. Moreover, this ability to respond in a particular direction guides a trait’s adaption. His theory is often called the theory of inheritance of acquired characters or the theory of use and disuse of organ.

The following examples can be cited to disprove Lamarckism. 1. The eyes of a voracious reader do not increase in size and power with increasing age. 2. The constantly beating heart maintains a constant size through generations. 3. The piercing of various body parts such as external ear pinnae is not transmitted to the progeny.
26.
How does paracetamol act?
Sol.
Paracetamol contains acetaminophen and is thought to act primarily in the CNS, increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, COX-1, COX-2 and COX-3 enzymes involved in prostaglandin (PG) synthesis. Unlike NSAIDs (Non-Steroidal Anti-Inflammatory Drugs), paracetamol oracetaminophen does not inhibit cyclooxygenase in peripheral tissues and, thus, has no peripheral antiinflammatory effects.
27.
What's hyperbaric oxygen therapy?
Sol.
It is treatment involving the use of high partial pressure oxygen. It is employed in cases of carbonmonoxide poisoning.
28.
What is a cell biology?
Sol.
Cell biology is that discipline of science which deals with the study of structure, biochemistry, functions, reproduction, behaviour, genetics and evolution of cell.
29.
What are unicellular organisms?
Sol.
Each unicellular organismconsists of highly specialized cell capable of performing different activities of life and capable of independent survival e.g. Amoeba, Paramoecium, Euglena.
30.
What is cancer?
Sol.
Cancer is defined as uncontrolled mitotic proliferation of cells due to loss of contact inhibition. It leads to the formation of abnormal growth (of a body part) which may be benign or malignant. The cancer cells are undifferentiated and actively dividing cells.
31.
Can unicellular organisms get cancer?
Sol.
No, as the only cell representing the unicellular organism must be fully differentiated while for cancer causation at least one cell must be undifferentiated to undergo uncontrolled mitotic proliferation. Thus, it is possible only in multicellular organisms.

KVPY INTERVIEW - 34
PRASHANT ARYA I am Prashant Arya, a student of XII standard (Year-2012) studying at Resonance. Last year I participated in the KVPY fellowship examination and cleared both its stages, written as well as personal interview successfully. The entire process was a great learning experience for me. The written examination helped me brush up all my basics as it focused more on the concepts than on tough and lengthy calculations. After getting selected for the next stage, I was actually nervous for the interview, mainly because of face to face interaction. But I have to say, the panel of examiners made it a really fruitful and fun experience. They were very polite and informal, asked me about my areas of interest and questioned me accordingly. I was given sufficient time and encouragement to explain my answers. There were challenging questions too but they were more interested in the approach than the final answer. They even asked me about my future goals and gave me valuable advice regarding the same. After this process, I have gained a lot of self confidence and my knowledge and presentation skills have certainly grown. I also want to thank the KVPY authorities for being very cooperative when I requested them for a change in my interview venue due to some reasons and they managed it. I feel obliged that I was a part of this process which has boosted my determination and my desire to keep learning.
PALAK JAIN “I’d say the interview was easy going…nothing to be tense about. It is more of a cordial discussion. We weren’t asked very probing questions or high level subject based questions…just the basics”.
I want to share my views about facing the interview . For performing well at the interview: 1. Select the subject at which you are best as your favourite subject. 2. Study the topics which are a part of your syllabus . But study them deeply. 3. While preparing for the interview : Maths : See to it that you have learnt the proofs of many formulae but not just mugged up. As many of the questions they ask are proofs of some difficult formulae but not solving the problems.

“Be careful that you don’t make blunders. Whenever you don’t know an answer the best thing to do is to say that you don’t know the answer.” If you bring in an irrelevant concept they will question deeply about the concept. Be prepared to write answers on the board.
AKASH ANAND I found the syllabuses interesting, and they gave me a wonderful opportunity to open my mind and gain a lot of knowledge.
In my experience venue of the Interview changes every year, and so everything might be related to it. I don’t mean to frighten you by saying this; I guess it’ll be more or less the same. My suggestion is that you should be well versed in your subject. The rest is a matter of chance.
The best part that I liked about RESONANCE, training me for KVPY is that they are always there to solve the tiniest of your queries at any time of the day. Also they pay utmost attention to the individual profile and guide regarding the individual profile.
I would like to thank RESONANCE which provided me a correct path. The mock interview provided by the faculty helped me a lot to perform well.
