Agoda Senior Software Developer interview questions

Applied online at mid 2020, got contacted at around September. I got into a phone call with one of the principle engineers, very friendly. We talked a little bit about my projects and what Agoda is doing. First round was a take home test with Java, which they gave me a week time to complete . Nailed that one pretty well. The test content was to write a data compression program. I can't specify the details as it is unfair for other interviewees. Second round was done by the hirinng team manager and a senior engineer. Round of coding and some more questions about my experiences. The coding question was a brain teaser. Right after the second round I was approached my the head of department. Telling me about what they are doing in agoda right now. Two days later I got the offer that I asked for. However due to personal reasons I had to decline but in general the interview process was a good go.

interviewer didn't show up for the zoom interview, then hr emailed asking to reschedule. On the new date the new interviewer seemed confused, didn't know who I was or have proper questions for me..seemed I'll prepared. Managed to move to next round, supposed to be 4 zoom interviews in 1 day. After the first 2 interviewes, hr emailed saying they'll have to reschedule the other 2. Couple of weeks passed, didn't hear back. Emailed hr enquiring about my application, didn't hear back. All in all very unprofessional and very ill prepared.
