Square | Phone | HTTP Replay

YOE: 2.5

I was asked this question on the phone for a Square interview.

I was given this JSON file, it had pairs of request and response objects, around 10 total.

I had to replay the request and assert that the response was the same. I had to do it on my own IDE with screen share and I could google/use any library and language I want.

I bombed it pretty hard, as I had never written custom code for making HTTP requests before.

Curious to see how it would be done in Java.

The JSON file looks like:
