Meta Platforms, Inc. is an American multinational technology conglomerate based in Menlo Park, California. The company owns 3 of top 4 social networks in the world: Facebook, Instagram, and WhatsApp. More than 3.5 billion people use at least one of the company's core products every month.
One of the best parts of Meta's growth culture is that there's no additional work required for engineers to go up for promotion. No promotion packet, no additional reviews, and no extra documentation.
Promotions at Meta are lagging, which means that you must be operating at the next level before you get promoted to that level.
Your manager will need to advocate for your promotion in the calibration meeting. If your manager doesn't support your promotion, your chances of success are near zero.
Comparing Meta to other companies such as Google:
Discuss your path to promotion, and what projects are required, at least 6 months before the performance cycle.
Think about key people in your team and adjacent teams, especially those at higher levels, and keep them updated on your progress toward promotion. You need the support of people from higher levels.
Finally, keep in mind that levels are private at Meta, so no one will know how quickly (or not) you're getting promoted.
