We’re a very small team with little experience in hiring but got approval for a new engineer. Basically HR will look for people through the usual channels and I think we have a reasonably good job description. Unfortunately the coding challenge (a 30h+ take home) is atrociously difficult and doesn’t really reflect what we do. On the other hand I think the false positive rate would be low. FWIW it’s a Linux application and it might be difficult to only count on experience from the CV.
Any ideas how to build a good challenge from scratch and what time constraints are reasonable?
I used to let engineers submit code/a project of their choice for my team to review. We would then have a technical interview and it would be partly inspired by the code provided. Do something strange in your work? Well now you’re going to have to explain it and justify why you didn’t do it some othet way. It wasn’t perfect, but I hired a bunch of devs that way.
