Perguntas de entrevista de vagas de Robotics Software Engineer da empresa Unipart

Was given a 16 question test to do that took a good bit of time to complete properly. There was Only one question I did not answer due to not understanding the question. However I felt I had answered all other questions correctly (due to the type of questions you knew that you were either right or wrong when submitting it) but was told it wasn’t good enough and was not even given a mark? It was a massive waste of my time just to be basically ghosted after submitting it.
