Agoda Senior Software Developer interview questions

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.
