Titles in startups really don't map meaningfully to titles in BigTech. You can be called a VP in a startup with 20 people under you in the org chart. That empire size is equivalent to "second level manager" in a FAANG, and FAANGs know this. When FAANG acquires a startup with 20 people, MAYBE the CEO gets a nice title, but most of the startup's acquired employees get Senior Worker Bee titles.
