When I was brought on board as a developer (or "billable resource" as we came to be known) it seemed like the ideal job - great benefits, decent salary, friendly staff, and work that was interesting and challenging. I even moved my family 150 miles to relocate to Manchester because it seemed like such a great fit. There was talk of professional development opportunities like training and code reviews, but it was just that - talk.
Sales will promise unrealistic timelines for delivery to get a client, and management will expect the deadline to be met, even if it means requiring the staff to work on holidays Thanksgiving and Christmas. The company culture, if you can call it that, is to run their production staff into the ground and replace them.
