It is a very nice program.
The interview itself is laid back. No hard questions. They have great diversity of clinical sites: university hospital, VA, Kaiser, but residents do not look or say that they are overworked. PD is great. residents are very happy there. Drawbacks, just as others already mentioned: location. I asked one intern about social life ther and she said that"you need to look for it". On the other hand Davis is only a few miles away. Housing is less expensive compared with other places in CA. Studio for about $800.
Hope it helped.
