You must fit with the culture to succeed here - Technical Training Specialist Regeneron Employee Review

The company is growing too fast for its own good, leading them to, in my opinion, compromise quality for speed; create inadequate resourcing for the work that needs to be done; and promote unrealistic work/life expectations. If your personality and values do not fit with the dominant personalities and values, you will not fit and likely will not last long here (or at least, not be happy). In my experience aggressive personalities do better.
