Before the Commencement of the interview wishes them good morning or good afternoon which will put a really good impression on the interviewer, never let the interview be in question-answer phase always try to turn in a friendly environment. One more pro-tip which I did in my interview when the interviewer asks you about yourself after telling them about yourself ask them their experience in Infosys in a polite way, in my case interviewer was 25 years experienced, and I ask them how she manages it, I know sometimes it doesn’t sound good, but at the same time, it shows you have more interaction skills and make you different from others.
