Interview Preparation Tips

Interview preparation tips for other job seekers - One of the worst company I have given interview,
The HR named Shubha A contacted me a day before interview that are you available for interview, I told yes.

After that interview has been scheduled, with interviewer soumyashree rout , I have given all the answers which she asked for and what did I get an acquisition of cheating in interview, I even showed her my surroundings that I am not cheating, and how come such dumb people are allowed to interview.
