Isn't interview strategy to answer questions in a way they want you to answer rather than honestly? For example, if asked "why do you want to work for this company?", you say "because it's a great company, I want to pursue a career in field "X", etc.", rather than "because I have a mortgage, car payments, etc. and so desperately need the money, I'm willing to rub elbows with you shmucks on a daily basis". So why would these tests be any different? I miss the good old days when they weren't commonplace.
