Technical Interview Imp

Brainteasers are a complete waste of time.
Laszlo Bock, SVP of People Operations - Google
Few professions seem so openly hostile to their current members as software engineering... we still regularly throw away huge groups of talent for not perfectly answering the latest hip algorithm question.
Danny Crichton, TechCrunch
Nothing will force companies to move on to better techniques faster than losing appealing candidates before they even get to interview them.
John Evans, Journalist & Software Engineer
