I applied through a recruiter. The process took 1 day. I interviewed at Operative in Mar 2017
Interview
First round with developer was normal and went well.
Second round with manager/ senior person was horrible, the person have no clue what he is asking , he has some answers in mind and won't accept any thing else. Most of the question are bookish and silly .
Would not have worked with even if I got offer .
Advice : try to interview candidate based on position you are hiring .
3 round process
2 technical and 1 hr.
