We try to avoid bringing people in who aren't going to be right for the company or the role, there are times when that's not clear until the onsite interview. Any selection decision is going to be based on mutual fit and the interview process is designed to help determine fit as quickly and as accurately as possible. You're busy, we're busy, it just makes sense to use everyone's time effectively. That said, I'm sorry to hear about this experience. I can't tell what interview you are referring to, but would be glad to look into the situation and understand what happened. This isn't typical. Can you email me at stephaniekempa@xrite.com? Thanks
