Yes, I agree with Barney on this one!

As "they" say, character counts.
As the "day" fast approaches, you could do worse than think through what your real motivations are ... and be ready to answer questions along the lines of:- "why do you want to work in a hospital"? You know, patient care and all that good stuff.
It is, after all, not everyone's cup of tea.

Be sure to be clear that the "patient comes first - always". If you can feed that one into the conversation at an appropriate juncture, so much the better!
And it wouldn't be a bad idea to spend a bit of time making sure you have a least a basic grasp of what goes on in the typical hospital departments.
... in my opinion there is very little actual electronics knowledge needed for an EBME technician ...
These days, that is.
