Different companies have different broad cultures, and different subcultures within teams. Some companies just don't have a sense of camaraderie built into their broad culture.
One thing that people don't always understand, and I always point this out to people I work with, is that your professional relationships are much more important than the company itself. Everybody is going to move on from their current job some day. When that day comes, they will benefit from having strong relationships with past team mates, either by knowing folks who can help them get new work, or by knowing folks who they can bring in to tackle projects at the new job.
Your professional network is one of your most valuable assets in your career. The people you work with are real people, with real families. Relationships with great team mates are more important than the company you both work at now, and will outlast your time at that company. Camaraderie is key to that whole scenario. Make sure you reach out to people you respect and enjoy working with and tell them how much you value that professional relationship. You will both be better off for it.
