To answer the question of waterside81: Yes, I rejected somebody just because I did not want to have an 18 year old kid working with us that calls himself 'very very conservative'. I do not care much about left or right wing. I just do not want extremists. :)
And I am pretty sure I got rejected myself at least once because of my political views that collided with the business model. Which is perfectly ok and a very understandable reason.
