I received a call on a Tuesday for an in-person interview on the following Friday. The interview was a three person panel. Two of the people on the panel explained their positions, the third and also the main interviewer did not explain his position in the company - even after being asked directly. There was a follow-up call for potentially a second interview. The caller asked, "can you come in for an interview?" and did not expand if it was a second interview or if it was an initial interview for another position I had applied for. I could not make either time because there was very short notice (the following day).
