WORST INTERVIEW PROCESS!! These guys make fools of everyone. I waited for 3 hours in their premise for the first round of interview. One of their talent recruitment team members came over there and started explaining why did it take so long. My first round went really good. The interviewer got impressed . He called HR in front of me and confirmed for next round in the upcoming week. But then I didn't hear back from them. I tried to follow up over email, but no luck.
