So far every job I've joined since finishing school in 2012 I've been the "smartest person in the room". It's been incredibly frustrating to not have peers to learn from technically.
It was so bad that I left my city (Recruiters and the jobs felt very toxic to me) and became an expat, started self learning what I wanted until I could consult enough to sustain myself.
Now I joined a large company for a large project in asia and I'm STILL missing people I can learn from.
I'm reaching my 30's, and have only worked at small to medium places with near zero mentorship.
