I came away from school with very little too Windshear
It is always something I fretted about when filling out job applications to major airlines. It didn't seem to matter in the end. I fly Medium Jets (737/A320 class) for a major airline now, about 2 years away from being a Captain I am told. I notice that most of my colleagues are in a similar position. I shouldn't worry about it, your performance in the sim is usually all the companies really care about come interview time.
