Being hired with Merck is like an IRS audit. I went through ten weeks of intensive training that included daily testing,verbal practicums and 10-12 hr days of studying and a constant threat of being sent home (I've seen it and people break down from the stress). I've been at 7 am grand rounds, made calls all day came home,changed my shirt and then went to an evening speaker program to finally return home around 11pm. I've worked conventions and gone to Merck meetings on week-ends. Spent my week-end on policy tests or a home office cubicle generated spread sheet,that my manager demanded yet never read. I've endured field visits from poorly trained tryanical managers who made my life miserable. It takes about 120 seconds on the phone for Merck (without cause) to lay you off. Is the pay good? Yeah it's (seriously) OK. Was it all worth it and would I do it all again ? No.
