The in-person interview process was a little tedious and slow, that's how I expect it to be, though the good part is you get to know you're out at the end of the day. However, they won't share the detailed feedback for some time. If they want to keep you on hold, they might notify you later based on the requirements of the candidates in their team.
The rounds mentioned were a total of 3 rounds in the email. However, there was another 4th round, which was a basic HR round.
The best part about the interview process was that if your resume is interesting, they will ask about it, except for basic DSA questions.
All three interviewers had my resume open on their screens instead of a predefined set of questions that they needed to ask.
The DSA questions were based on
Binary Search
Two Pointer
Basic String manipulation.
If you have worked with AWS, that's a huge plus point. Be ready to answer everything AWS.
Overall, a positive experience if you don't mind spending the whole day with them.
They also give you lunch, snacks and coffee.
Unfortunately, I got out at the managerial round, but at the end of the day, it was a great experience for me and at the end of the interview process, I got something to reflect upon.
