I was a summer intern for Genentech last year. It was a great place to work, and I definitely learned a lot. I was in a commercial role, so I did not see as many pharmacists. The med comm positions tend to have more PharmDs. There are several paths you can take to get into pharma/Genentech. Some have worked in hospital for a decade and then moved over, others have done a fellowship, and I have friends who were directly hired out of pharmacy school (but they did work in internships during pharmacy school).
Med Comm Assoc Scientists will make around ~100k while Med Comm Scientists make around 120k. Of course, this also depends on how well you can negotiate, but you can use GlassDoor to get a ballpark range.

As the post above stated, it is harder to get into CRDP vs a fellowship. There are currently two tracks within CRDP: traditional and MCCO. PharmD's usually qualify for the MCCO track and not the traditional track (due to the lower requirement of years of required experience and MCCO being geared more towards working in payer strategy).
If you look on LinkedIn, traditional CRDP are mostly selected from top MBA programs. The PharmD's who are MCCO all have worked in pharma before pharm school and had pharma internships during pharmacy school.
For CRDP, you could always do fellowship 2 years -> CRDP 2 years
