Booking.com

• Located in Amsterdam
• Okay salary and lunches

• Extremely outdated tech stack. As a backender, you may get a chance to work on some cool systems. However, still, most of your day will be focused on digging in spaghetti Perl code. You'll not be able to transfer your knowledge (almost) anywhere.

• A/B testing obsession. Making the smallest change will require running weeks-long experiments to validate if it's useful for the customers. Not worth it if you like to iterate quickly.

• Incompetent middle management will put you down. Never before have I seen so many people struggling with mental health issues (depression/anxiety).

• Non-existing HR. The salaries are so screwed that new hires can get up to 15k EUR/year more than people who have worked in the company for 5-8 years. Recently, some developers left and came back within a few months to get their salaries readjusted.

• As a frontender, it is a NO-GO zone. You'll not do ANYTHING useful.

• You'll be working with tons of people from 3rd world countries. Diversity, you say? Not really. We hire them because it's harder to change a job quickly when you need to worry about your visa/family. Most of them wait 7 years until the magic barrier of obtaining Dutch citizenship.

I came as a motivated individual, been 'strongly overperforming' in terms of Booking performance for almost 2 years, and left, depressed and tired of everything I saw here. Please, don't do this to your career.

There's nothing you can do at this point.
