I haven't interviewed for it (haven't even put in my applications yet, lol), but I have to go to OHSU all the time, and it's amazing. The people are all so ridiculously nice, everyone's always got something sweet to say, and the environment is pretty laid back, all things considered.
That might just be because it's Portland, though. I've lived and traveled over two continents (North America and Asia), and I've never found a place I liked better than Portland. It's beautiful, ecologically friendly, healthy, and safe, and the public transit is amazing. There's a lot of research done there, too, and a lot to love. Plus, I've never found a more welcoming and tolerant city.
(Can you tell I'm planning to live in Portland when I go back to America? I'd stay there as long as I could, even with the rain it notoriously suffers)
