On top of the large amount of process and the one week sprints, we also four different dev teams each working on their own microservice app which was tightly coupled to the other apps in the company. Every team had to deploy at the same time, and if one app went down, the other apps went down with it. The company's platform was essentially an ecommerce site that could have been one medium sized monolith, maintained by a single team of 5 or 6 developers, but instead we had 20+ developers, several dev managers, a scrum master, and a large QA automation team. I guess you could call it premature optimization.
There were also plenty of issues on the business side that prevented the company from truly succeeding. The place was a bit of a clusterfuck but it was an excellent learning experience.
