Oncology to CCU...

I'm cross posting this for more views since my interview is coming up!

Hello everyone! I've been a nurse for a couple years, most of which was oncology and medical. I keep falling into oncology positions because it's where my experience is, but recently I feel really pulled to critical care. There's a few hospitals around here with ICU/CCU positions posted and I've been applying for them. I have an interview in a couple weeks and I was wondering what I should be looking for in an orientation program, having no critical care or cardiac experience? I'm very willing and able to learn and I have basic acute care experience, but I just don't know what to look for in an orientation to make sure I'm properly trained. In the hospital I used to work at, people with no critical care experience were started in a telemetry unit first, then worked into ICU, so the idea of starting straight into ICU is intimidating to me!

Thanks in advance!
