Booking.com Developer interview questions

I applied directly. I took an online Hackerrank test which was fair. After that, I had an interview with a recruiter. After that one, I had a one hour interview with two very lovely engineers. they asked me a programming question and wanted me to solve it and talk about it. After that, I had a system design interview with two lovely engineers as well. Final step was cultural fit with a manager. Very important step and he insisted on knowing technologies I used, the way I am currently working in terms of Agile and other details from my CV. Interviews ended and They took around one month. it was very tiresome. The last interviewer told me I should get a response within five days. It has been 14 days and no answer to any of my emails from the recruiter. Over all, time consuming as well and in the end you don't get a response in time or anything.
