I've had a similar experience where I joined a new company, worked for four weeks, had a performance review, and was told that I had lost the confidence of my coworkers and if I don't improve my productivity, I'd have to be let go in a month. I quit immediately. I was contributing from day one. I had introduced unit tests to their code. I implemented a Stripe integration for subscriptions. I added new features. After receiving one of my questions, the senior dev would take a long hard look at me, thinking of the dickest thing to say, then he'd say it. The responses were always condescending and rarely helpful. I became afraid to interact with him. No matter what I did, I did it the wrong way. He didn't offer solutions, just criticism. When I mentioned that working with this guy was incredibly difficult, my employer said that he understands, but this individual is so good at what he does, it's just something they'll have to deal with. Life is too short to deal with these toxic individuals.
