I applied through a staffing agency. The process took 1+ week. I interviewed at Aventis Analytics (Noida) in Dec 2015
Interview
It was a telephonic interview, so I felt pressure while answering tricky questions. Also the interviewer's, also the client's reaction was neutral to each and every answer. He was like "OK, no problem, next question". Technical questions weren't much difficult but analytical skills too were tested wherein they provided real life case studies.
