Preguntas de entrevista para Upstream Works

I never had the opportunity to complete the interview. Initially, a date was scheduled, but a few hours beforehand, my interviewer emailed to say she was unwell and needed to reschedule. On the new date, the interview was again canceled just hours before, this time with no explanation. I followed up to understand what had happened and to attempt rescheduling, but I never received a response. I found this experience disappointing and unprofessional, as it ended up wasting my time.
