There are 4 rounds in total (Machine coding/ DS Algo/ Design/ Hiring Manager).

I had a terrible experience in the DS/Algo round.

The interviewer came up with a problem from "Geeks for Geeks" and expected me to spit the solution. The interviewer is shamelessly checking for solutions in the middle of the interview. I couldn't stop laughing. "Flipkart" seriously?

The irony is he didn't even understand the entire solution himself and his laptop got shut in the middle. He changed the problem to an easy one after failing to recollect the solution. LOL

I have read a few reviews like that before the interview and I didn't believe them. Now they made complete sense. Don't become a crappy company with robots testing for knowledge.

Tree and graph problems.
