FB's interview loop was WAY harder in NY vs SF for a senior position
FB is considered SF based since it has HQ there.
Ah sure, NYC based companies are lower-end. Best bet is to go for satellite offices.
Try Jane Street, might be harder:)
Hope you know OCaml!
I'm pretty sure there's no correlation between interview difficulty and location, assuming the location is a major city with no dearth of talent.
Talent does vary by city.
I can give you a basic problem to solve and you can do that. People aren't only testing the knowledge you have (not much as a fresh grad) but also how you approach problems and get over hurdles.
