Not worth bothering if you get the following one. It was just disrespectful: They give you a take home test about implementing a REST service. It had a very poorly expressed description by someone that does not know English well. Then after submitting a solution, it gets accepted and the next stage is scheduled, but after that everything gets cancelled. It seems they did not really reviewed it, and no feedback has been given apart of saying as a negative that the solution uses Spring heavily. I cannot explain why using libraries and frameworks is a penalty, but if that's the case then it would have been good to make it clear in the description (as they let you use any JVM language) before wasting anyone's time.
