Preguntas de entrevista para el puesto de Sr. Python Developer/Software Engineer en eLife

Just was asked to do an assignment for which I took precious time out of my schedule and instead of spending some time to go through that assignment or atleast giving a proper feedback, I just got the head of engineering did not like it. I am sure that the assignment wasn't there to be liked but rather to be assessed and a proper feedback to be given. If you ask someone to spend there time then spend equal time for them as well. Highly unprofessional attitude and lack of etiquettes can be seen.
