The process took 2 days. I interviewed at BT Group (Bengaluru) in May 2017
Interview
Interviews spanned over two days, with 1 round of written, 3 rounds of technical F2F and one round of Managerial F2F. After all of this they said you are selected and HR round will be setup soon, but never came back with an offer.
Interview questions [1]
Question 1
Technical questions on big data. Not very difficult but the whole interview process is very lengthy and not worth it as the HR may not even respond after all of it.
The process took 2 days. I interviewed at BT Group (Bengaluru) in Apr 2017
Interview
There were 5 rounds of interview spanning 1.5 days. 4 rounds on day 1 and one Managerial round on day 2. After all this, I never get a call back from the HR. I had taken 1.5 days leave to attend the interviews but BT HR doesn't care for your time.
