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 take a HackerRank test. The test was short: I had 20 minutes to choose the correct answers from 20 questions.

I suppose if you have some experience with front-end development, you will do okay on the test.

The same day, I received an email with positive feedback about my test and an invitation to choose a time for an HR phone interview.

The HR interview lasted around 30 minutes. I answered 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 a small JavaScript exercise. I used jQuery heavily for this exercise. I was glad that I had brushed up on my mastery of jQuery prior to the interview.

The next day, HR called me to provide feedback and to say that I was invited to Amsterdam for the final day of interviews. Of course, I was super excited.

On the interview day in Amsterdam, I spent around 5 hours at the Booking.com headquarters.

I had three interviews: two technical and one on business awareness.

The most interesting technical question was to recreate one of the Lodash array functions.

Another question related to the implementation of UI elements on the page.

HR called me a few hours later and invited me to come to the office again the same day in the evening or the next morning.

I decided that the sooner the better and came back to the office in the evening. Here, I received the offer.

I want to thank all the guys and girls who took part in the recruiting and interviewing process at Booking.com; you do a great job!

My recruiting process was a quite positive experience.

Questions about the implementation of UI elements on the page. The element should be added dynamically to any part of the page.

Implement one of the Lodash functions.
