Booking.com

Technically, it is one of the companies that will challenge your skills as an engineer at scale. Not the biggest scale out there, but still.

The company runs on lots of in-house built infrastructure, which is an opportunity for engineers to expose themselves to a wide domain of knowledge and experience.

Almost all managers I've worked with are under-qualified to manage people or processes. The majority can't take a decision in a timely manner. Decisions are always too late to be good. No accountability whatsoever. A manager that fails to deliver once is still trusted to deliver a second time. And if he/she fails the second time, why not trust them with yet another deliverable, maybe a more critical one!!

Over the years, the company has lost LOTs to the good devs for reasons always related to management.

Success in Booking.com is more of a success to give promises with catchy wordings to a group of managers who like you. As for actually delivering, or what the impact is, it does not matter much. You will hear "data-driven", "measure the impact", etc., in meetings, but history, more than once, proved it's just words!
