Kinda weird. I think the interviewer just hung up on me. She asked me if I am willing to work any time. I said, yes. She asked you might have to work extra hours at different times, you will have to be flexible, is that alright? I said, yes. Then she asked do you have any other commitment, educational or anything like that. I asked if 20 hours is about the maximum hours I can get work there? She said depends on your availability. I said if I cannot get many more hours than 20, then I might have to take up another job as well. And, either the line broke or she hung up. I couldn't call back as it was an 'unknown' number and it was past office hours. She didn't call again, either.
