Agoda Customer Service Representative interview questions

The process was really long, over 2 months with many interviews and an math/logic test. Most of the interviews were quite good, interesting questions, case studies. Just on of the last ones with most senior person the really basic strengths and weaknesses questions. I expected more. After 6 interviews no offer since being overqualified.

3 interviews and a language test that is done online. HR was very helpful throughout the process and replied in a timely manner. The interview with the hiring manager however was last minute, long and some questions were invasive and irrelevant. The process took 2 weeks and after the final interview I received a rejection with no feedback. I emailed and asked for feedback since I did not expect to be rejected (I passed 2 language tests and the 2 other interviewers gave me positive feedback so I was curious to know where I went wrong). But I did not hear back from them. It was frankly a waste of time.
