FAQ: How do engineering levels line up across different tech companies?

Here ya go!

Super short article. When I moved to the Bay Area and switched companies, it took me a while to figure out how to map engineering job titles to experience levels. A friend pointed me at a helpful site, levels.fyi, which I sampled to create the following job title map. Enjoy! [I may follow up this article with a post on expectations at each level, which is another FAQ.]
