I applied internally and went through a couple of in-person interviews with the supervisor and would be colleagues. They asked questions about my background and professional experience. All in all, the interview process was stress free.

HR round, writing test, and Technical round were the part of the entire process and they were pretty difficult. The process took a month for each round. Follow-up had to happen a lot of times especially after the last round. They kept me hanging but after two months told me that I am not selected without providing me with any feedback on my interview.
