Pros: A really innovative place, with good benefits and good career development. You will learn a lot and meet many passionate people.

Cons: Since the business is huge and the app was built years ago, there are some legacy parts, but they are migrating into some fresh stuff.

Pros: 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.

Cons: 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!

Pros: Pay is good. Some teams have really nice and smart people.

Cons: Corporate structure makes the company look like something else entirely between units. A lot of unnecessary pressure, bad players, corporate gamblers, doing everything but what's actually needed.
