Hey, one of the Triplebyte founders here. We do using coding problems but we try hard to mitigate the issues you bring up. We give candidates a selection of problems to choose from and we'll often explain how to solve a problem if it seems they're getting stuck. We're less interested in sudden flashes of insight and more looking to see if someone can write code and implement ideas they talk about.

We know it's still not perfect though and our goal is to keep experimenting to find what works best and be open about the results. As we mentioned in our last blog post, we're planning to offer take home tests as an option for our next experiment.
