When I was in college I used to work in a big studio’s QA department during summer breaks. The building we were in was situated where QA lived on the 3rd floor and all development and management were on the 4th and 5th floors. As a result regular QA rarely ever met with or talked to the developers, and it felt very much like we were not part of the team.
This was the top shared concern among QA employees when the company was taking input on the designs for it’s new building. We must have made an impression because the next summer we were moved to a cheap used warehouse down the street while the Dev teams got a new building built specifically for them.
