I think hiring is really steered to avoid hiring idiots. After all it&#x27;s the interviewer that will have to answer if they hire someone who can&#x27;t do the job. So all questions are very technical&#x2F;random and difficult. Most of these people just lookup stuff from textbooks and fling them at interviewees. It eliminates the top and bottom contenders while catching mostly people who just came out of school (or ridicilously smart).
