Lets say you have a job at a respectable company, Microsoft in my case. How many YOE of experience would one need to reliably be hired as L4 at FB/Google. What about top tier startups like Uber/lyft/dropbox/square etc? I understand the answer will vary greatly based on your type of experience and interview performance. But as a general rule, what would be a reasonable YOE to transfer to L4 and what would be considered a fast YOE?
Can check out the averages across L4 data on http://levels.fyi
