Frustrated!

I was in sales before becoming a trucker. One thing I learned in sales is that if you know what objections you are going to get, deal with them upfront before the customer raises it. I also learned you have to get past the gate keepers and get in front of the decision maker.
In trucking, that means, first, get past the gate keeper, the secretary who screens the calls or the recruiters. If you do some research, you can find out the name of the person who makes the decision to hire someone, that is who you have to get in
front of. For example at a company like werner, you have to go past the recruiter and get to the safety manager.
You already know that your being fired will come up. Make it a positive. Make it a reason why they should hire you, and lead with it. Keep in mind, you don't need to tell them how bad a lot of the training is with training companies, they already know it. What you need to convey to them is how that experience has taught you, and why you are a better candidate because of it.
If it were me, I would spin it like. " I got into the industry and was very green, I went with company X, having very little understanding of many aspects of this industry and was at first devasted and bewildered when I was let go. Since then I have had a chance to reflect on what happened, do some research and now feel more assured that being a professional driver is something I really want to do, and although I made some mistakes the first time out of the gate, I beleive it has offered me the opportunity to be better prepared and even more commited to my success as a professional driver...."
When anwering questions about your past company and your trainer, sandwich all your answers. Example, "having not been taught how to alley dock at a 45 at school. I was very appreciative of my trainer for taking the extra time he did to teach me, however, although he was a wonderful guy, had some trucking experience and was able to show me many things, I believe he was also inexperienced in being an instructor and found it stressful, which was complicated by some personal things he was going through. I belive that when it came up, he was in a difficult situation, he either had to say he was struggling as a trainer, which would have cost him, or that I was struggling as a trainee, I believe it was a bit of both, that we were not a good fit as trainer and trainee. I am no longer as green as I was then and feel that a better understanding of what I need to do to insure I gain the training and experience I need"

Anyway, you get the idea, the situation is just what it is, you have to paint it in a favorable way. The first thing is to not have a defeatist or victim attitude but a winning one.

 

Very well said. You must have been a car salesmen! Anyway that was some good advice right there.
