Career Advice About Booking.com

Engineers need to submit a packet of their work for their manager to review.

• Below level F, the manager and senior ICs will decide on the promotion. These promotions are considered "local" and are easier to push through.
• Starting from level F, the packet is sent to a promotion panel to decide your fate. The manager is not part of this panel.

There's no limit to how many engineers can be promoted on a single team. This can lead to occasional situations where an entire team consists of senior engineers.

At Booking, the minimum time in the role before a promotion is 1 year. Exceptions to this are very, very rare, which can be a source of frustration, especially for early-in-career employees who are clearly performing at the next level.
