I'd like to tell about the second part about interview because the first is extremely personal. They sent me a Codility test and in fact was not hard. Unfortunately I had not done a Controller test in Codility before so I tried do more thing then the test was asking for ... For exemple I tried to log application even though they were not asking about. In Tried to do a Restfull Controller using some DDD like to break application in layer because for me it's not good to inject a Respository directly in a controller so I wrote a Service Interface that was implementing a concrete Service impl. Theys asking me to return a 200 http code in a Post when was creating a resouce and I really wrote in test that i was agrreeding with them because the most correct was to return a 201 created. I wrote all method for them like Post, Get, Put and Delete I user a Spring Data to access their database but how I said before I haven't done Codility Test before so I was not able to test the api because the api was really simple in real world I have done hader things then test api. I felt really sad because I really know the skill and knowledge their need to their clients/customer and be a WAES consultant but they just sad to me that I was not able because I din't have the skill. In the test was 3 question, one about algorithm really simple but how as a Java Engineer test used a Java Lib and it don't pass in a 100% codilty test and had a db test to do
