Pros
Employees - despite the many, many, downfalls of this company, they somehow manage to hire talented people with great attitudes (but it's probably due to the scarcity of life science jobs in the LA area). Even then, though, these people soon leave because Phenomenex is notorious for underpaying employees. Don't let the fake reviews fool you...it's absolutely true that they pay well below industry averages.
Cons
They claim to be making an active effort in improving employee development, but it's really a clever way to try and exploit ambitious workers. They do this by piling on added job duties and responsibilities without giving even a mention to increasing pay. In reality, they're just taking advantage of employees, avoiding hiring much needed personnel, and protecting their bottom line.
