Orientation process for new RN employee/fresh graduate

When one lands a nursing job for the first time, what's the typical orientation process like? Is there a period of mentoring where the newbie can learn firsthand from an experienced staff member? I'm a US citizen foreign grad looking to work in the US and I'm concerned that I'll probably need a lot of catching up to speed especially when it comes to the more advanced machines and equipment in the US. Thanks.
It varies from facility to facility.
It does vary, but usually, yes, there is a period of orientation, especially for new grads. Sometimes hospitals put new grads through mini-internships when they are first brought on to make sure they are competent and comfortable on their own. It is a good question to ask at your job interview!
