    Easy Interview

    Application

    I applied through a staffing agency. The process took 1 day. I interviewed at One97 Communications in April 2015.

    Interview

    I registered through talent grids. First round was aptitude + technical MCQs. It was easy and I cracked it. Second round was screening by rockstand . I think it's 3rd party staffing agency. I was told due to some technical difficulties, my online screening was scheduled 3 hours later. In that screening wannabe geek offered me the job opportunity to some other company, and didn't ask me any questions. I was surprised, and amused, and I had a wry smile on my face. I said that I was shortlisted for Paytm screening. Then he told me that I should not tell that to anybody. No surprises, that I did not get invitation to F2F interviews.
    Whatever this rockstand thing is, it's very unprofessional. Good luck hiring fresher talent with such approach.

    I applied online. The process took 1 day. I interviewed at One97 Communications (Noida) in August 2015.

    Interview

    It does not take more than two hours and a single day. There were one written round, after that a technical round.. then again there was a technical round. and after that a HR round.Questions were all related to the field, But you should be proficient what you have done. either you have done something if you describe or you have not if you are not understandable.

    The drawback i found was obviously the management as company should give a feedback or reply to the interviewee about his selection. A good level company always do that.
