I went for the F2F (Face-to-Face) round at Flipkart's Bangalore office after an online HackerRank round. There were supposed to be four rounds of interview, so I had planned for five to six hours.

I reached there at 10 am. The process was very slow; they were able to finish the first round by 2 pm. After that, they repeatedly asked me to wait for 30-40 minutes more.

I waited until 8 pm (YES!). By then, I was hungry and thought of leaving. I told the HR/Recruiter that I was leaving because it had been around 10 hours and they had conducted just one round of the interview. The HR then started laughing at me. I mean, seriously, they did a very lousy job of keeping candidates waiting for 10 hours with only one interview round, and then they laughed at me too.

The worst interview experience of my career.
