On the other hand, 2 hours for a tertiary interview after already spending time out is a reasonably significant investment of time for someone who likely already has a position and which I’d suggest isn’t widely required for positions outside of technology. Certainly no management position has a 2 hour examination on processes or people retention strategies in addition to the usual coffee shop discussion or panel interview. I’d be more in the line of reviewing a GitHub if available or a sample application or even just some concepts, implementation can happen in a range of languages but as long as the core is solid that’s what I’d be focusing on that. The most egregious version of this I’ve seen was an interview for an infrastructure position where the challenge was a generic coding test. That’s fantastic if you want a generic developer but it won’t tell you anything about architectural patterns or common sense. In any case, I’m just a developer and these tools are usually aimed at managers, and since this can at least give a non-technical person a hint of whether a candidate is suitable I guess that’s valuable on its own. I’d be very interested in the tech behind the product offered by this team to evaluate the candidates though...
