The technical part involved case scenarios, problems, and their solutions, plus some general programming language puzzles, which was the best part. Then there was a non-technical HR round to check my behavior. The offer package pay is decent, better if you've worked in reputed companies before to get a good package. Bonus amount is just okay.

Finally, there was an HR round with general questions about my willingness to work.
