How prestigious/helpful is a internship at Genentech gRED?

Hello!

I am a current grad student in chemistry and was offered an research internship opportunity at Genentech. Here is my dilemma: I have fallen back on my research and was thinking about skipping on the internship to focus on finishing up my current research project. However, the more I read about the internship, the more it sounds like this would be a bad idea; it seems that the selection process is very competitive and it can quite helpful career-wise.

Has anyone done the internship? Was it helpful to your career? Should I just focus on my research instead?

Thank you all for your advice!
