They said I lack experience, even though I received great feedback after my technical round. Later, I checked the hiring manager's LinkedIn, and he himself joined the company as a senior engineer after 3-4 years of experience, which is very weird, to reject someone on that basis.

The interview process was smooth and well informed well before the entire process. There are two rounds, the first is coding challenge once I cleared that round, and the second is creating a presentation for the DevOps solution to a problem statement, and the interview is based on that presentation.
