My 2c... I do work inside a very knowledgeable team, so I can relate to some feelings (although the guys here are quite cool). 1. You were hired. That probably means your colleagues approved having you with them. Part of what you feel is the famous imposter syndrome. On the other hand the best way to handle that attitude from someone else is to be honest: "I don't know, I haven't worked with that, I've not experience on that" are valid answers and I hear them from the most experienced guys. Nobody mocks them. If you're open and honest and your colleagues mock you, well... No need to say you should move away :) 2. Not unheard of. 3. No idea, but success and accomplishment gives a sense of power. Power rottens a lot of people. This is just another step on learning about life. I've been there and I still got some of those feelings, despite everyone around me being extremely supportive to each other.
