I had the same experience and the comment about relaxing resonates with me. Coming from the startup to the big company I could not understand why people leave the office at 5pm. There would be another few hours to work. Also lots of meetings. As the previous commenter said. Relax. I guess you will have a broad skill set from your background and actually in big Corp the nice thing is that with this broad skill set That you can engage in so many different projects. And it is tempting to do so. But you only have this much time a day, and it will not be easy to accelerate your pace. This frustration can be bad for your mental health. So my advice is relax. But also don’t forget the thoughts you had when joining the big company in the first months. Maybe keep a journal. Because you probably had good ideas but might get overwhelmed by the complexity of the big Corp. If you have not read the “Accelerate” book, I would recommend this as well. Also you can observe Conway’s Law in its beauty.
