Occidental College Infrastructure Systems Administrator interview questions

Mainly an email with five questions. First, few questions are designed to weed out those who can't start right away and have certain salary expectations. The last question goes over a project you worked on recently. After a few days, you get an email from an internal resource that someone will reach out to you for the next steps. Days go by with no call or follow up email. I noticed the position is no longer available online. Then a few weeks later the position is open again. No courtesy, inform applicants to expect a followup call or email, then nothing.
