First round was a hackerRank and I did not pass all tests but was luckily move onto the next round. Next round was a phone coding interview. The interviewer was pretty cold so I ended up not doing very well

First there was a coding challenge. If you pass at least half the test cases, you can move on to the first interview. After that, there was an interview, which was followed by two more interview. Finally, there is a final round. After this, they select a few interns.
