It's mostly been awkward at work when co-workers or my manager make comments like "you've shipped code like this before" that's followed with negative feedback and a implication that I should've "known that wasn't good enough" or "wasted the time of a reviewer" even though the code seemed simple enough for me and passed tests. I really can't tell if I suck or just work in an incredibly toxic workplace?
