The hiring process was fast and efficient. I applied online for the position of front end developer. A few days later I received an email with an invitation to do a hacker rank test. The test was short. I had 20 minutes to choose right answers from options on 20 questions. I suppose if you have some experience with front end development you will do the test ok. The same day I received the email with positive feedback about my test and invitation to choose a time for hr phone interview. HR interview was around 30 minutes. I had been answering expected questions - about my previous job experience, why I want to work for booking.com, and theoretical questions about a/b testing. Next was a technical interview via Skype with two developers. It lasted 45 minutes and I was required to implement small Java Script exercise. I used JQuery heavily for this exercise. I was glad that I brushed up my mastery of JQuery prior to the interview. The next day hr called me to provide me with feedback and to say that I am invited to Amsterdam for the final day of interviews. Of course, I was super excited. On interview day in Amsterdam, I spent around 5 hours at booking.com headquarter office. I had 3 interviews - 2 technical and 1 of business awareness. The most interesting technical question was to recreate one of the lodash array functions. Another question was related to the implementation of UI elements on the page. The HR called me a few hours later and invited me to come to the office again the same day in the evening or next morning. I decided that the sooner the better and came back to the office in the evening. Here I got the offer. I want to thanks all the guys and girls who take part in recruiting and interviewing process at booking.com, you do a great job! My recruiting process was a quite positive experience.
