Yes I totally understand but I think the nature of the problems to solve in Java are not related with this complex algorithms. I mean, I have been training myself in generics, OOP, SOLID principles, Clean Code, Design Patterns, TDD, BDD and some others for the last three years.
How I am supposed to show my skills in one hour resolving a low level algorithm in a web IDE (this particular case)? All my "low level thinking" is pretty oxidized.
I am building just another AWS automation tool but hiding any AWS related concept. Integrating a lot of services like MongoDB, Redis, Cassandra and all this cool hyped stuff.
