Naukri Corporate Sales Interview Questions and Answers

Interview preparation tips for other job seekers - Prepare well for the interview. I was from a science Background and a Masters's degree holder in Pure Sciences, so the interviewer was very pissed because I wasted the resources of the country, and now I am seeking a job in sales.
So, he hardly asked me any questions, just for namesake. Why can't the interviewers be shown the profile better by calling us for an interview??
Utter waste of time.
