Wolfpack Digital interview questions

Hello! I have being contacted by a recruiter via a phone call and I accepted to start the interview process. After that, they decided that my CV is good to move on the next step, The technical interview was a take-home assignment: to design and create a back-end infrastructure of a store. The assignment itself was average, so I thought that I can expand and make it as close as possible to what it means to develop a solution in a span of several days. The problems arose after I completed the assignment: It took them almost 2 weeks to evaluate the code and have a response from their side. The feedback was the usual "we decided to move on with other candidate" even though I completed all the requirements and even more, and the arguments provided for this decision are weak, to say the least, My experience with them is overall negative and I regret that I invested time and effort with them.
