i live in gurgaon, i interviewed at cvent for the post of IT Recruiter. There were 5 rounds and i cleared all of them i went there twice for these rounds, but after the last last round there was no response from them, i waited for them for a week. HR Taran she was texting me all the time before the last round but when it came to final verdict she got chocked i believe. there was absolutely no reply from this Hr. i texted her and asked her so many time about the results but no response. this is how a Hr should behave? this was the worst experience of my life ,i totally wasted my time.
