I'd try hard to find another company. I might be in the same boat to a point. I just did an interview, wasn't informed a driving test would also be done at the same time.......didn't do too hot on it. I have very little experience in a 10 speed, my current ride is a straight 6. Funny thing is, I drove an 18 speed about 6 years ago for about 15 minutes and took to it like a duck to water. My muscle memory kept going for the next set of gears that weren't over there in the 10 speed. He was amazed by my backing ability though, so I got that going for me!
Heck I was dressed to the nine's to make a good impression for the interview, wrong footwear on so I couldn't feel the pedals and feels funny wearing dress pants while driving a truck!
