These companies has made computer science students simply dev ops who never use algorithm (except during interviews). So many computer science students don't go beyond cracking the coding interview. This is really sad.
I'm suggesting that if you feel the interview process is flawed even from the company's standpoint (i.e. not screening for the appropriate skills) your best approach might be to reverse engineer the interview (i.e. get better at answering the questions, instead of actually developing the [perhaps irrelevant] skills being screened for).
The Tardos book that I think you're referring to is a $100+, 850 page CS textbook with the goal of making you an expert on algorithm design. The book I suggested costs $30 at is focused on a specific goal of getting through the interview.
I'll grant, however, that there may be better resources for this (and I'd be very curious to hear what others think those are).
