Set up a phone interview via email. Spoke to the employer over the phone for about 25 minutes. The interviewer was friendly and ask questions regarding my availability and interest. She closed by stating she would follow up via email. I received a job offer that week.

It was short since it is just an assistant job, and it was not too hard. Mostly focused on my precious working experience. I was asked about my PC skill, relevant experience, my current situation.
