Preceptors

What is it that makes a person a good preceptor? What are things that they do that makes them, well, not so good?

Does the preceptor need to adapt to the orientee, or should the orientee adapt to the preceptor?

I would like some input from others, your experiences, so that I can sort through what went wrong with my day shift preceptor.

So how did your preceptor teach and treat you? What worked the best, what didn't work at all?

Thanks in advance. :)
