Well, a while back I was asked to help out with an emergency project on another team with a major client for a major contract. An arcane system that no one (not even I) knew how to work, that was incredibly frustrating and old. Essentially they wanted a major new system built off of a very old, limiting, and opaque tool. I won't go into the details of the tools for confidentiality reasons. Anyways, this meant I had a huge task to do, no one to go to for help, and many top levels within both ours and the client company overseeing and getting stressed over it. This project was originally scheduled for 2 months, but due to scope creep and a lack of push-back from the PM in charge of this project, they begged for me to continue to help another month, after which they asked me to continue till the end of November after which I would be on my 5 week vacation. Anyways, the reason I was quitting was partially because of all the frustration, stagnation (no learning opportunity) of working on that system, and because of the main person I have to work with (our product team is ~9 people but this "side" of it is only 3, and 1 is a junior with less experience/know-how). During my whole time there, this person I had to work with only trained me on the existing system only when he felt like it, but only ever scratching the surface. Any further questions about this unfamiliar domain (very niche service for extremely niche work) that I was unfamiliar with and unable to learn from anywhere else was met with "I'm busy.", occasionally followed by expletives and heavy sighing. Often times this person would also get incredibly passive aggressive. Long story short, it was very stressful working with this person and the general environment at the company is very heads-down, hard working, so virtually no other social interaction was ever had (or very rare).
