I applied through a recruiter. The process took 1 day. I interviewed at Tiger Analytics (Pune) in Oct 2024
Interview
I recently interviewed with Tiger Analytics and was quite disappointed with the process. The interview was rescheduled a day earlier than originally planned, which I managed to accommodate. Unfortunately, during the interview, the panelist appeared unprepared and seemed uncertain, giving the impression that the decision to reject me may have already been made. This experience left me questioning the company's professionalism and interview process. Based on this encounter, I will not be seeking future opportunities with Tiger Analytics, nor would I recommend the company to others.
