Medzilla

Medzilla is probably my favorite search site for pharma/biotech jobs. The reasons are simple:
1. It's free
2. Many companies and headhunters post positions here
3. You can apply directly from the site
4. There's a great message board system where people are much more sincere and kind than some of the other sites. If you ask a question, you can expect an answer from an experienced rep (usually) who may already be with that company.
