Ask HN: Does your company measure the long term benefit of interview code tests?
9 by traviskuhl | 3 comments on Hacker News.
If your company does coding tests during the engineering interview process, (how) do you measure the long term effectiveness of the tests? Do you keep internal metrics comparing candidates' score to their long term impact/success at the company? If yes, what have you learned from the results and how have those learnings impacted your hiring process?
