Interview Preparation Tips

Interview preparation tips for other job seekers - Not at all good experience. Looks like the structure is baffled now after pandemic hit. First of all HR people, they have so much attitude that you can't even ask them any query regarding your JD or project. Secondly there are many rounds but it all depends upon the interviewer mood only and only. Because you are not hired for a direct project, so if the interviewer is egoistic and high attitude, then it's difficult to get positive feedback even if round well all well. Disappointing experience. Suggestion would be to put right people for talent selection. If people are kept in similar way, every new candidate might have negative experience.
