Definitely Impostor Syndrome, not a real impostor. Large companies move slower and have more money. That's simply how it is. I remember my second project at a large bank; I needed to do something, talked to a bunch of people, and finished the thing in about two weeks. That was not good. I was part of a big team that was tackling some complex stuff, and me running ahead of the pack was disruptive. Take it slow, be part of the team, etc. We then made a planning with the team, specified everything that we thought needed to be done, and did the thing exactly in the planned 14 sprints (which is still pretty fast and accurate for a bank). Big projects at big companies have complex contexts and complex dependencies, and can serve highly specific abstract needs. It can be frustrating when things move slower than you think they should or could. And it can be frustrating when it takes a long time to grasp a project. It's not unusual if it takes a few weeks, or even months, to get up to speed. In between a bunch of big projects for various banks, I've also done one small project for a friend making an online game. Suddenly, I'm pushing changes to production on my very first day, when on other projects, it can take me a month to get up to speed. It's them. It's not you.
