I can see that because I've experienced it. That said, at most places I've worked at over the decades, there was a lot of mentoring, both formal and informal. One place I worked at, however, was just depressing. No one communicated except via emails. Informal discussions about how the system never happened. No one even went out to eat together No one was hostile... it was just... cold. To me, it was just weird and I got out of there ASAP -- but I suspect many there liked it that way.
