1 online coding test, received the link through Naukri.com. Then I was flown over to Hyderabad for F2F interviews, had 3 long technical interviews. Then another technical skype interview. And lastly an HR interview. I only did LeetCode. And some geeksforgeeks. Datastructure and Algorithm is enough. Superb experience. HRs are very good. Interviewers were very smart and gave off hints that make your brain start to work.
