I too heard this before interviewing and accepting a position. What I've come to find is it was probably started by two groups: 1) those very few who may have been slighted by a manager and put on a plan, pushed out, etc. and maybe didnt deserve it 2) Those who don't work very hard and are stuck in the old pharma mindset that they are owed something for showing up. If you are truly interested in succeeding and working hard, you will be successful here. I've worked for the big boys and small biotech in both sales and management, and the big difference here is there is nowhere to hide. Upside is, if you do well, you'll be rewarded. There is no culture of fear, but a culture of high expectations, which, if you are any good, you won't have a problem with. Good luck.
