Booking.com IOS Developer interview questions

The interview process was good to start with. Very clear cut. 1st round was an online coding test in HackerRank. Once cleared this, the HR called for a telephonic round. Here we discussed on what we would like to improve on the App, Discuss about my projects, am I ok relocating to Amsterdam etc. Next was supposed to be a Skype round with live Coding (surprisingly they decided to skip it for me as the Online coding was very good in their opinion). Next was an Onsite interview in Amsterdam. The interview process in Amsterdam was a day long with 3 rounds. 1st was a technical on Objective C. Second was a DS round and last was a round with Technical Lead. Attending the in-person interview i got the feeling that they were looking for someone who has mugged up the solutions though. Moreover, also their Approach towards an Applications architecture seemed as if they are not doing it in a very modular way and hence did not like my solution to their architecture problem. But that is my feeling.
