You misunderstand. There is a very common class of engineers that have no problem describing and explaining their work to their peers. They do have a problem with doing it in an adversarial and stressful situation like an interview. I've seen it happen to engineers I _know_ are good. Also, over years of actually engineering hiring pipelines for software engineers, I've seen no evidence that its easy to weed out the good talkers. Quite the opposite I think it's one of he hardest things about designing these pipelines. > Don't take those jobs if you want to be hireable I guess? My point about this is not on behalf of the person being hired, its the person doing the hiring. Your process creates false negatives. False negatives in hiring pipelines is nearly as expensive as false positives.
