I've been in interviews where those stupid "I have three balls and want to guarantee the ball I pick is red" questions get asked, and what I've noticed is if they want to hire me, I can just take vague guesses and they'll help me along, but if they don't want to hire me, they'll sit coldly, watching as I flounder about. By the time I've sat down in the chair, a lot of times the person hiring has already made a choice. I'm not charismatic enough to reverse their choice, but I'm not antisocial enough to disqualify myself if they already like me. The thing I learned about applying to jobs last time I went through this is that if your primary goal is obtaining a source of income, you need to send your resume to ~10 people a day, every day, and go on every possible interview, and do every possible thing people ask you to do. You'll still lose a lot of jobs to these techniques, because they're effectively random, but since it's random, your odds of success increase with volume. Eventually you'll hit a position that you do just randomly happen to know the algorithm they're looking for, or they don't ask CS theory questions (I'm self taught, so theory is a weak point for me as well), and you can talk about/demonstrate your actual job qualifications, rather than some contrived talent that's entirely irrelevant to the position.
