They may ask about mechanical aptitude, which is critical for a lift mechanic. I suggest do a internet search on a mechanical aptitude test and understand what they want before the test. It really is a simple thing like the way a car engine uses the main drive belt to crank the crank shaft, alternator etc. The question would be, what the direction of rotation of the individual wheelS are? Things like this would be what they want to know.
Here is an example of what I mean.

I have that number in my phones contacts as "elevator guys" so I don't get faked out.
After getting your call you'll drug test (paid for) probably within a day or two and you're off to the contractor who picked you up. They wouldn't be calling the hall for help if they didn't likely need it after all.
That's what I assume at least, hopefully this next week you get a call Vet and can fill us all in.
