Agree with KE...any checkie worth their salt doesn't want to fail you.
I always say that check performance is a reflection on the training department. If too many are failing, either the system is failing the trainee (more likely) and the training captains need to take a close look at themselves, or the trainee is just not up to it (less likely in my opinion, but it does happen)
For goodness sake, don't let it put you off taking a job with them. It's part of being a professional pilot and you will be putting your licence on the line every 6 months for the rest of your carreer....get used to it!
You know you have turned a corner when you actually see a check as a learning opportunity and an chance to demonstrate your capabilities, rather than a knee trembling, fear fest where the nasty old checkie is out to get you.
We've all been there, and it takes some longer to get over it than others.
Good luck!
