Getting promotion used to be hard. Google engineers used to stay in E5 for many years and getting to E6 was considered a great achievement and many considered it impossible. Similarly, getting to L6 was a big deal, and getting to L7 was considered exceptional. As far as I know, it was Meta who broke this tradition. If an engineer had a large enough impact, the engineer would be promoted. So, it was not uncommon to see a engineer in Meta get promoted every year or two. Nowadays, it has become a norm for engineers to expect to get promoted every two years.
