The team was friendly and approachable—relatively young but with some industry experience. It felt less like a traditional interview and more like a chance for them to gather external insight on a live technical issue (for free!). That said, asking candidates to tackle current problems is a practical way to evaluate their capabilities. The product itself is straightforward, with the complexity lying in the robustness and sensitivity of the biosensor. One of their challenges is designing rigs to help the scientists with their work on understanding the products sensitivity. Microneedles aren’t new, but it’ll be interesting to see if they can successfully commercialize the technology.
