Started with Skype interviews, I had 2 which lasted about 45 mins each. I was mostly asked about what I do and how would I do certain things and some technical questions. Interviewer mostly noted and let me talk. Few days later, I was invited to visit Bangkok for F2F interviews. There were 4 interviews each lasting 1 hour. Some verbal technical discussion but most were white-boarding. Questions were mostly on architecture and scalability. There were some algorithmic questions as well but not complex like graphs or trees.

First round was a DS algo round, where 2 questions were asked. Medium level, nothing fancy. In second round was given a hld of a booking system i had to tell what improvements i would make to the system.I mention a lot of things but was rejected cause i did not speak much on the QA side. You have to know about testing frameworks. I thought it was unfair by him to reject only on that basis. Hasn't changed the company himself in 10 years.
