Ask HN: What do you look for when reviewing a take home exercise?

Hey HN, I’ve recently applied for a job I’m very excited about. They’d like me to do a take home exercise as part of the interview process. Without going into too much detail, I need to build an interface that allows a user to manipulate data from an API. I can use whatever tools I would like. What separates a good example of a take home exercise from a bad one? It’s a fairly simple exercise so I’m considering using vanilla js but wonder if I should showcase my experience with modern frameworks and tools instead. Is there anything else I should consider? Thanks!
