I don't get it why people complain all the time and still use it? Even their parent company Priceline UX is much better, then there's Expedia and other sites. I would never book anything on Booking because it's plain ugly and keeps design from 1998, even Craigslist looks modern in comparison.

Their hiring and interview process, at least in product management - it looked like they are fishing for fresh ideas on what to A/B test on their website. All the talk was focused around it. Answering the questions they didn't give a single direct answer only extremely vague ones. Red flags all around.
