We had a brief Skype call with HR. She was a nice lady and introduced the company. Then, they gave me a code test. This is where the problem begins.

First of all, they only have one task, and have used it for a long time. Several of my friends applied for this company before me, and they always received the same task: a money transfer API.

My friends' tasks had fatal issues. I studied their mistakes and made mine foolproof. I spent a week coding it, more than six hours per day. Everything was going great. I thought that was the cleanest code I had ever written. Then they rejected it.

The reason?

"mvn test fails."

They didn't mention that I should use Maven in the task description. There was absolutely nothing.

I wish someone had at least read the rest of my code and given me detailed feedback, just to respect my wasted hours. They just scraped it in five minutes.

Design and implement a RESTful API (including data model and the backing implementation) for money transfers between accounts.
