Preguntas de entrevista para el puesto de Software Engineer - Java Developer en Onwelo

Worst interview of my life easily. Interviewer was rude and made me feel bad about myself for every wrong or incomplete answer I gave. My answers were far from perfect, but it doesn't justify ridiculing the interviewee. The interview was supposed to last 1,5h, but it was cut short after 20mins by the interviewer. Will never interview again with this company.
