The hiring practices at a number of tech companies are somewhat legendary. The recruiting process at Microsoft, for example, often entails answering a number of extremely challenging technical questions and perhaps a few brain teasers. To work at Google, one often needs to have a minimum GPA threshold from an esteemed University just to get in the door. Itâs even been reported that Google CEO and co-Founder Larry Page has personally approved each of Googleâs 24,000+ employees â Page apparently receives a brief application packet for each applicant that summarizes his/her qualifications.
