Interview Preparation Tips

Interview preparation tips for other job seekers - Overall experience is very disappointing from this company. There were about 7 candidates and the process took the whole day. In the end, other than me, there was one more candidate who gave the final round. It's been 2 months they haven't given the result (Though it's pretty clear).

At the end of the interview, they asked us to leave and said results will be declared within that week. But no response, so I sent a mail, they said the process is still going on. After 3 weeks I again sent the mail and to quote them, 'both of us were neither clear reject nor clear select'. So they were still deciding and gave me a very definite response that will let me know the final result by the end of the week. I did not get any response and did not even bother to follow up again.

Okay, firstly, there's nothing like this clear reject/select shit, the candidate is either ideal for the job or not. You people should give more credit to the candidates and have the courage to reject them. Recruiters need to be a little sensible while hiring. Rejection is not an issue but not getting a clear/firm response. So, please if you don't find a person suitable for the role, just tell them and help them move on. Else they'll keep thinking in the back of their mind that they might have a chance at this company.

Secondly, the Noida office is really depressing.
