Airlines won't be interested in your exams - if you can put first time passes on your CV then that is a bonus, but they will be more interested in your performance on the CPL and IR flight tests if anything.
However, the MOST IMPORTANT THING is that you are a person they like and can get on with. It is all about personalities really, so if they like you you will get a job, if they don't you won't.
