Get hired through your network: people you've worked with before, who know your OSS work, etc. I vouched very strongly for a former colleague of mine, and the team basically just had a series of chats with him to get to know him, reviewed his github, and never threw him a homework problem or coding question because they considered my strong endorsement of him (and them knowing my character) to be enough. Needless to say, it has worked out well for all involved.
