Round 4: HR (Final Round)

The interviewer just introduced herself and also asked me to introduce myself. I was asked the reason for choosing PSIT as my college. Also why I have chosen the happiest minds. It consists of only such basic questions which were followed by a briefing of the offer.

** Tips: Be real in front of the interviewer, just try to use appropriate words and frame them in a proper manner instead of faking the interviewer. Also, work on coding basics and prepare DSA very well.**
