As far into my career as I am at this point, I've both a finely honed radar and zero tolerance for toxic bullshit, but as a new developer, it's a whole lot harder to have both the self-confidence and self-awareness to recognize that the reception you're getting isn't because you're an unqualified idiot, it's because Sr. Developer Jim's dad was an asshole and Engineering Manager Bob doesn't know how to or have the confidence in his role to rein in his Sr. Developer from berating the new grad for things that new grads do until emotionally balanced mentors teach them not to. I have good friends who've spent a lot of time in therapy undoing what toxic workplaces did during vulnerable years.
