First of all, you had to clear the coding assessment forwarded to you on HackerRank, then, you had three interview rounds, your technical skills were tested via some question and answering, and a simple task was given as an assessment, which would hardly take 5 - 10 minutes, then questions on your projects mentioned in the resume, and after clearing these 2 technical screening rounds, you would have had an HR interview.

They asked a medium level SQL query, then a simple question on multithreading in Java, and asked questions on projects in my resume.
