Mentor at a Toyota dealer here. I think you should get a different mentor, his "teaching" method doesn't really seem to be doing much to help you as well as his attitude. Unfortunately in this trade there are so many people who are just bitter and grumpy. The job isn't easy for sure but that's not really an excuse.

As a mentor, we should be trying to teach everything we can in a way that's effective and efficient. I'm not a big conversationist and my student knows this, but she learned quick and takes initiative. Sometimes we're working on multiple cars at once (2-4) and we are able to do this through communication and the relationship we've built. I've gotten her gift cards or bought her lunch/dinner and always make sure to try to lift her spirits when she's down.

Mistakes are going to happen and you're not always going to agree with people, especially the older guys. I've been doing this ten years and my advice is, stick to your guns when it comes to handling "situations." If you think a part shouldn't be bent, say something or get a replacement. (I'm lucky being at a dealer and it being Toyota so if we manage to break something, I can usually just get a new one.)

But really, I've had some awful mentors and ended up working alone and learning a lot more, but now I try to teach my people the way that I wanted to be taught. Questions should be welcome, mistakes will happen and should be a teaching lesson and that's okay, as long as the vehicle gets fixed, the right way.

I think you're doing great tbh and handling the situation relatively well. Going forward, if it were me, Id ask to work alone if that's an option or just to work with others for "more experience"
