IMHO, any interview (phone or onsite) for a tech job that rejects a candidate because of some deficiency is found in technical skills during the interview, whoever scheduled the interview is at fault. That manager/HR-person just cost the company easily a few hundred dollars. Such determination of one's technical chop should've been made well early in the screening process, from past work or online tests or coding example (like take home project type). Interview process is expensive. It takes 1-5 hours of manhour from your company. It takes similar or more from the candidate. Think about how much you pay each engineer. just my 2 cents.
