||Cramming and/or trying to misrepresent yourself is a bad idea. Reviewing things can be a very good idea. A good interviewer who is willing to explore and dig will determine whether you are good or not. Unfortunately, many interviewers use a predefined set of questions, and if your current focus is in a different area, you may look worse than you are.
I still remember an interview back in college, with a company who is known for their good, technical interviews. They asked me a question which was right out of a data structures class. Having been 6 years since I had taken the class (I took it in high school), and not having had to do a similar problem since then, I was rusty on the material. Failing an interview that I would've aced 6 years earlier was frustrating. Had I reviewed the topic a little bit, I feel I would've been able to much better represent myself.
That being said, the little bit I looked at the said link, it didn't really seem that useful.
