I can imagine an embedded developer unable to do that, they never do HTTP requests and it's a nightmare to implement in C or C++, a web developer in python/ruby/node should do fine.

It's selecting for languages and candidates with built-in support for HTTP and json and base64. It's far from a 1h problem if the candidate has to find working libraries for each of that.

Depends on an embedded developer. It is very handy to know TCL or Python so you can script your hardware or create provisioning/testing scripts. And with the whole IOT thing, HTTP requests in C became much more common.

Deffinitely right. This is for positions in a SaaS company where the developer would be mostly doing backend or frontend code.
