Buy some algorithms books. Brush up. In the beginning, if you're stuck on a problem, peek the solution. After a number of them you'll be able to start doing them yourself. You're learning a new skill, it's called the bullshit-google-algo-interview-problem-solving skill. It has little to do with most real problems, and when you do encounter the real problems, you'll talk to people and look up reference material anyway. Just like how the SAT has little to do with predicting academic performance, this silly little game has little to do with predicting real world programming performance. It can be a valuable exercise to be exposed to the material, but by no means is it a pre-req for being able to succeed at sw eng. Plenty of people garner the correct resources, study for this and get fancy jobs where they go on to spew out absolute garbage in code form. It is meaningless. Some companies recognize the folly of this, ask the recruiters.
