I have ~3 yoe but I live in Iowa. Does this mean anything when applying to big companies like Airbnb/Google/FB in Seattle/Cali? Or would I basically be considered a new grad and start out as an L3 if I pass the interviews? I've been studying for about 2 months now but I am starting to get wary about it. Would I even be considered to interview as an L4?
Also, make sure you understand what things to expect in the interviews here in the Bay area. And how to prepare. There are excellent resources online like leetcode, hackerrank, educative, interviewbit, GitHub system design primer etc.
Again, don't think that. Where you come from rarely matters if your concepts and prep are solid.
All the best.
