You will never know how many rounds, even after getting joining letter they will ask for one more interview. Hr round. Technical round, written test in some cases. Its not necessary technical guy or your stream expert will take your interview. Just show your confidence nothing else. Already so many illitrate people working from so many year.

Very nice and beautiful but took almost 2 hours . He asked questions from leetcode and had techical quizzes also I will rate the interview as medium difficulty so that's about it
