Agoda Senior Developer interview questions

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.
