I was interviewed for a faculty position at ISU. Let me say this that the department was full of politics with no clear guidelines. Colleagues were pulling legs of each other. Candidates were already lined up and the university was inviting "unrelated" candidates to complete hiring formalities for others. Be prepared to notice what you would not like to experience during an interview at a serious institution.

I applied through higheredjob.com About 3 weeks later, I received an interview invitation. In the first-round interview, I was interviewed by 5 professors at ISU. The interview is around 45 mins. Professors are very nice, BTW.
