Booking.com User Experience Design interview questions

I was a straight coding and front-end development position. It has nothing to do with UX, most exercises and tasks involves talking about code infrastructure and doing menial HTML/CSS stuff.

I applied online in January 2018. For Amsterdam 1) Someone from RRHH send an email: asking to complete an online test to assess general coding skills (CSS and HTML). The test is in HackerRank. When I enter I have an image of a banner from booking page. Something really easy. I recommend you take a look in the structures of the banners in Booking page. 2) I had a call with someone from RRHH (no video): - He told me that in booking in general you are coding between 40% and 60% of the time. - Do you have experiences validation your designs? - Imagine that you are working for booking, and you made 2 improvements for the site but you can only applied one. How you will prioritized it? 3) I had an interview with 2 designers (no video). The interview is divided in 3 parts: -One : They asked me about my job experiences. How is the most proud job that I made. My roll in that job. Why I'm proud. How I manage feedback with the clients. How was the work process. They want examples. So be prepared with examples for all. - Second: They show me an image with a grey rectangle that has inside 3 squares. They asked to make the code to do the same. -Last: I should have prepared 3 improvement to make in the site. I attached the images with the changes and documentation like gestalt and other info about UX. They asked to me select One of my improvements, said why? How would you define the success of the new implementation? What metric would you use? If the metrics shows an increment in the clicks but it any changes in the conversion: do you think that the change is successfully or not? why? If increment the clicks, the conversions and the cancellations do you think that the change is successfully or not? why? - At the end you should asked something. Have prepared 1 or 2 questions.
