This doesn't sound like Imposter Syndrome, but it also doesn't mean the problem is you or character traits about yourself ("not seen as reliable"). You're literally getting no support from your team. No manager and no assistance from the senior members of your team is absurd. How are you supposed to get better? Feel your feelings (like "I feel kinda like a disappointment") but don't project what you think other people are feeling or thinking unless/until they give you direct evidence otherwise like " I am not seen as reliable and definitely not known". Is anyone saying anything directly like that to you or strongly suggesting it? As far as the QA/Prod issue, HOW where you supposed to know? How is the next dev supposed to know? If your team (i.e. the senior devs) aren't providing documentation or operating procedures, then they're failing you; not you failing them. > I was sometimes assigned stories no one else on the team had done anything like before, so at times I couldn't even ask the senior devs for help. Again, if you're tackling issues that the senior devs haven't seen, then how are you working "slower" than them? They have no frame of reference of how long it should take. So how do you improve? You need to find a mentor (or even a therapist?). Someone, anyone who you can talk to and get an objective perspective on things. You're new (and that's okay!) but that also means that you don't have a reference for what's okay and what's not. It's not that you have imposter syndrome, it's that you think that causing sprint-slowdowns or prod issues is something unique and awful. They're completely par for the course. As far as the whole PIP thing, if you have no manager, who's going to put you on a PIP? If anything, you need to be raising a stink of how you're a junior without a manager and working without senior dev support.
