Agoda Senior Android Developer interview questions

I applied through Stackoverflow jobs for this position based on the Bangkok location. First, they sent an Hackerrank test(12 multiple choices & 3 problem-solving programs). Mostly, I answered all except 1 problem-solving question. They moved my application for the next round as Skype Video Call with Mobile Team lead from Bangkok. The interviewer asked very basic questions(OO Paradigm) from Java. I didn't given satisfy answer. So they didn't process my application for the next round.

Interview had 8 rounds. It started with hackerrank challenge. Then a skype discussion with senior developer. Then A small application that we need to optimize and fix errors. Then another skype interview. Once you clear these they will invite you to their office in Bangkok, there 4 discussion with Senior lead and managers.
