It was a very long process. After applying for the position an HR specialist mailed me for the phone interview. After the phone interview, they send me a test. After that, I got invited for a face to face interview and it also consisted of a conference call with a team leader from a different country. After that, I got invited for the final step of a face to face interview with the other team leader. I'm also working full time and they did know all about this. They did not give me an offer and said I'm not the right fit for the position! After all these steps! And this mail came from another HR specialist that I do not know. Interview questions were very hard for the last f2f interview. They asked the same personality questions again and again. I've risked my current job success by excuses to do an interview with booking.com but they're too rude and selfish to be a human. I completely understand that the HR specialist decided I'm not the right fit in the first interview or they do not like my test answers OR EVEN at the first face to face interview! But inviting to the final step and saying that I'm not the right fit for the position, it is not an acceptable ethical business work that I can not understand!

After sending my cv through their website a recruiter contacted me. We had a friendly chat with the recruiter in English, he talked about the company and the position itself.
