I had a similar personal experience. I was hired by the technical team at a very big company(after 6 interviews; 3 face-to-face and 3 remote), but the HR was not sure. All my experience before that was working for smaller companies. The argument the HR made was that I will not survive in the big company as most of my experience was with smaller companies. The HR was right. In a year I just could not stand the inefficiency and waste of talent at the company. I moved to another division within the same company. The same story repeated. I left the company after 2 years. Interestingly I was not the only one. This was a major problem at the company. But the company is so big that it does not even care if people leave as there are a lot of engineers knocking at the door every single day to get in!
