Perguntas de entrevista da empresa Smart Imaging Systems

The interviewer seemed unprepared for the interview. He was looking for something to test me on and ended up picking out a random part from a computer to model in solid-works. He never answered how precise he wanted the model and was mad that it took me longer than it should have, but his request was very vague and it left me confused. Also he ended up offering me $12.50 an hour only to then say if was not satisfied with my work he would just stop paying me. Not fire me, but just with hold payment for work already completed. Very strange.
