There was one brief phone screen followed by a half hour phone interview. Then there were 3 follow-up phone interviews with three different interviewers which each took about an hour.
During the first interview we attempted to log onto their fairly new HireVue online video interview app. Unfortunately, this app didn't work so all of my interviews wound up being phone interviews. My previous experience having completed online interviews with the another video application was amazing. So, I was surprised to learn that this one didn't work.
I felt like the first interview was mainly to pump me for insider information on how I performed the same job with a previous employer (which happens to be a Fortune 50 Company). It was also filled with standard behavioral questions. The questions weren't hard, but they can be a turn-off for some candidates. Especially since there is no evidence that stronger people are being hired based off of these types of interview questions.
The second interview was very pleasant and informative. The interviewer made an effort to get to know me as a person and as a potential employee. In addition to that, she also asked some performance based questions. The last interview, however, was another round of rapid fire behavioral questions.
Unfortunately, they were unable to schedule these three interviews back-to-back and I was only given two days notice to schedule. Just something to keep in mind if you have to take personal time off from your current job to do these interviews.
