Interview Preparation Tips

Interview preparation tips for other job seekers - I would say this company is full of fraudster specially their HR ' Anurita Bisht' she is very unprofessional, non ethical, and stupid i would say. I had cleared all their rounds inspite of that didn't hear back for managerial round there was drive happend for that where 6-7 candidates got selected after that they didn't provide any further update on MR round and for HR discussion.
This was very unprofessional that you guys conduct drive and didn't provide any update even after the selection. Totally waste of time specially their HRs are worst no response on call or emails.

I think this company is full of jokers and they made joke with job seekers candidate they have speciality in wasting canddates valuable time. I think legal action should be taken against such type of worst organization and HRs like Anurita Bisht (if I would say any worst word exist then she deserve that).

Very terrible experience i had, if you guys want to save your time and carrier please don't ever attend their interviews or drives these jokers will feel you worst moments.
