The biggest factor in getting a job is timing. If they need pilots they'll take anyone. If they don't then they can afford to be picky. Other than certain places like Ryanair most don't really care. And once you have 500 hours on type no -one cares.
It's kind of a moot point though isn't it - your bed is already made. Don't worry about exams, concentrate on getting yourself into a job. Start with the usual suspects, then think about getting your foot in the door with a non-flying role.
