G. Mark’s Answer
My first job was at IBM and then I was hired by Bell Laboratories. What I can say that pleasantly surprised me was that the people were, almost without exception, not only very smart, but very generous with their time. They were mostly having fun at their jobs and you could tell. And they were eager to help the new folks. And for that matter, to help anyone. It was fascinating, challenging, a lot of work, and I don't think I'd have preferred to do anything else. So I'd say, "supportive" is a good term. We were all a team and we did whatever was necessary to get the problem solved. Just great.
