I just took my boards yesterday, actually....just waiting to find out the results. I've been working full time at a Kaiser in the bay area. Equally MD/CRNA practice, with nerve blocks, high risk OB, spinals, epidurals, arterial lines, rare CVPs, high risk patient cases, etc...Good hours, decent pay, and good experience.
The interview process (for me) was more of a "get-to-know-you" feel. Honestly, most people can memorize information to get INTO a program, but their concern is more that you can make it THROUGH the program. They ask you questions about your experience too, but it's more of "Tell me the kind of drugs/procedures/patients you dealt with", not "What is the cellular action of Amniodarone?"
It's important to have a support system in place, because school is STRESSFUL....I can't emphasize that enough.
I agree about the experience in a bigger hospital (with more back-up people!) before you branch out. I thought about taking a job in a rural setting (3 room OR in a tiny town!), but thought that as a new grad, if I had an adverse outcome, my license might be at risk simply because I lacked the "intuition" of several years experience in my field, so I wasn't willing to risk it yet. I love my job here, and the people I work with, and that makes a huge difference, especially when you are just starting out!
Hope that helps!
