Sometimes it depends on what you consider an “interview”. There may be multiple stages of an application process where you are being evaluated, but you may not actually be sitting in a room or on the phone talking to someone directly. For example, my last internship while in university that ultimately led to my first “real job” looked like this:

1. Phone interview with recruiter
2. Online multiple-choice personality assessment
3. Recorded responses to on-the-fly questions
4. In-person competency test (Excel & SQL)
5. In-person case study
6. Presentation of test & case study answers
7. General interview with a panel of managers, HR, and a director

4-7 were all on the same day, but involved different focuses.

In the traditional sense, I only had 2 interviews where I was on the phone or sitting across from HR/managers answering questions about myself. Though this obviously involved many more steps than those 2 interviews. By another count there could be as many as 7 total steps or “interviews” taking place. Though they wouldn’t necessarily be able to drop me at any point, especially part way through steps 4-7 where they already walked me through what the day would look like.
