"When we decided to give the test to the development team (about 15 developers) — most of them got scores that were lower than our threshold (45%), despite them all being rock-solid developers. Also, there were some candidates who managed to get 95% and above — but would then just be absolutely awful during the interview — we would later discover that they were paying someone to complete the technical test on their behalf.

There is no substitute for taking the time to sit down and talk to someone."

That’s pretty good advice. Interesting read.
