What can I do with a masters in biostatistics??

I am probably going to get an MPH with a concentration in biostatistics. How does the MPH compare to the MS in terms of employability?? Also what kind of jobs do most people with this degree go into?? I heard most go into pharm companies and design clinical trials, analyze data etc… How much of the job is sitting at a computer and crunching numbers and how much is interacting with other people? Can someone with a biostats degree tell me what the average day at your job is like???

Thanks, I really appreciate it.
