    IT Engineer - Global License Administration Team Interview

    Anonymous Interview Candidate in Bangalore
    Anonymous Interview Candidate in Bangalore
    Application Details

    I applied online. The process took 2+ monthsinterviewed at Qualcomm in June 2013.

    Interview Details

    I had applied for this position in the first week of may 2013. I got a email from the Hyderabad recuriting HR stating my profile has been shortlisted and a telephonic interview was scheduled in the first week of June. On the day of the telephonic interview ( US Timings by US Engineer), I didn't get a call.

    So I sent a mail again. The HR rescheduled it again in the second week of June. This time, the conference codes and dial in numbers for the telephonic converstation didn't work. The Interviewer sent me a mail on my personal id and gave a new set of codes after half an hour. I dialed this number and about 100 rupees got cut.

    A very simple screening happened during the interview process. No technical questions asked. He just asked my experience on FNMP product. He conveyed that I'll be taking up a in person interview in bangalore later and then only the hiring manager will make an offer if I'm selected.

    Till June 20, no updates were given. So I contacted the HR and she added the Bangalore HR in the mail chain. The Bangalore HR after 2-3 email updates, came back and said she needed 2 more days since the interviewer was on vacation. After 20 more days, I didn't hear back from the Bangalore HR. Hence I sent a mail venting my displeasure and her reply was that "She was handling hundred interviews a week and she missed it/ it was one of the bad eggs".

    The HR doesn't have basic workflow ethics. That's all I can say. Very uprofessional
