I was interviewed in Dec 2024.
I participated in a coding round on their platform, which consisted of three coding questions in 60 min. however, their editor and compiler were quite inadequate. The event was held onsite, with 500 candidates arriving on January 11, 2024, at 9 AM. Approximately 100 candidates cleared that round.
I solved all three questions, yet we still had to participate in the second round, which included one coding question to be completed in 20 minutes. The question was poorly framed, leading to the rejection of most students. However, I managed to solve all the test cases.
The coding round comprised one question and was conducted on paper for a duration of 10 minutes.
