Booking.com Credit Controller interview questions

I was contacted within days for a phone interview, then followed two in person interviews. The process was very quickly until the last interview. I was told I was going to be contacted regardless of the decision. I waited for a week and half until I had to reach out to the recruiter to then receive and email that the position was filled within. That is fine with me, the fact is that i felt ignored and unappreciated. I took time off from work to be present for the interviews, the least I could receive was the same treatment I received through the beginning of the interview process. The communication was great until the last moment, it was easier to just let me know i was not picked, not waiting until I had to reach out.

It lasted 3 weeks. First they informed us for a group assessment. 12 candidates. we had a brief team work to present the what credit control is and the requirements/skills of credit controller. After that we every individual had a 2-minute role play about a phone call with a client. 10 days later i was asked for a 2nd face to face interview. I know that they didn't ask all the candidates.
