In last 6 months or so I have taken quite a number of interviews for technical positions and that has given me an insight into psyche of the interviewer. If we make a rough estimate that around 50% of the people who appeared for the interview have almost the same technical level then what makes the interviewer select one candidate out of the whole lot. The following points helps interviewer or at least helped me in taking a decision of whom to chose.
a) First Impression - You must have heard this a lot on many occasions that, “The First Impression is the last impression”.As soon as you enter the room where your interview is going to take place, you are going to make an impression on the interviewer and you have only one chance to make an effective impression.
b) Communication Skills - One of the most important qualities that makes even an average candaidate looks excellent is his/ her communication skills. If one can communicate effectively thats surely going to make a dent on the interviewer and you will be given some extra points for it.
c) Confidence - If one can present himself/herself confidently that is going to take you places. Your best bet would be to answer all question confidently, whatever you speak, say it with confidence that you are correct. If you don’t know answer to any of the questions it is better to confidently say that you do not know the answer than to answer incorrectly with your confidence shaking.
d) Truthful - It is very important to be truthful while writing your CV and telling about yourself during the interview, be it your qualification or your personal abilities or your experiences, one must not be lying. Usually the interviewer has enough experience to figure out whether the interviewee is being truthful. Even if it goes undetected in the beginning - it does not really help later when you get caught with such lies.
e) What make you different or what is your USP or why should we chose you for the position - You should have a well prepared answer for this one as this probably is going to be your last question and you have the last chance to make an lasting impression on the interviewer.
Do let me know if you find this helpful whether you are the one who is preparing for an interview or responsible for taking interviews.
