Not gonna lie, your code is pretty bad, no separations of concerns, no contextual logging. The position was for a senior engineer, your stuff is junior level at best. Don't lash people out for your inadequacy of the role.

Sorry but your code is not for HelloFresh. It's for GoneRotten.

Sorry but I have to be honest, your code is pretty bad. To me the true is, you are not good enough and that's it. You also were very anti ethical exposing the whole code challenging to your Github
