I've done, literally, hundreds and hundreds of coding interviews and an http api was a part of lots of them. Exported vs non-exported fields and json tags are about the only issues I've seen candidates hit in Go and I would just help in those kinds of cases. Python is marginally easier for many. The problem was java devs. Out of dozens upon dozens of java devs asked to hit a json api concurrently and combine results, nearly ZERO java devs, including former google employees, could do this. Json handling and error handling especially confounded them.
