Maybe I glanced over it but who did the candidates interview for? Were those just simulated interviews or are they working with companies that actually hire people? Or are they hiring for themselves? I'm very confused by what "success" means. The last paragraph indicates that it wasn't actually used for a hiring process? I see a commenter on their site has the exact same reaction. Either way I applaud every afford to improve the hiring process. However I'm a tad bit skeptical. They should release the dataset (unless I missed it) because it's pretty convenient that the results seem to indicate that hiring can be improved by a quiz which they could build and sell. I'd be interested in the following screening filter: Have a programmer at the company read through the projects the candidates supplied (as a replacement to "read CV") and then come to a conclusion of yes/no. No projects = no job offer by default. You can always think of a different approach for people with no projects if you feel like you should hire from that group. Possibly have multiple programmers read the code and discuss it.
