Sorry for the late reply. >what is exactly "exceptional enough", can you tell me how do you see exceptional enough? This will be purely subjective. For me - one thing, for guys in Facebook\Google\whatever - something else. Maybe they'd want to see that you are exceptionaly good with algorithms, maybe you can come up with desigh ideas quicker than most of them or at least other candidates. I can't tell. The point is - you will have to prove that you are so skilled that you relly didn't need that one yera at school, certificate, degree or something else. >what's etc Depends on reqirements for the position. For programmers this is usually algorithms and patterns, but this will inculde something else. Maybe protocols understanding, maybe deep learning, maybe working with graphic imformation. Just look for what they have in their jobs descriptions: www.facebook.jobs
