I video conferenced with 4 individuals and was asked behavioral type questions. They were very pleasant but also serious and I could tell they meant business. By the end I could tell that they liked me and was confident in a job offer.

This can be a long process to even get an interview - months even. Once you finally get a call from the HR recruiter - you will be prescreened and possibly scheduled for an interview. You will usually have a 3-4 person panel to talk with each taking turns with the standard "tell me a time" questions. Usually, there is only one round but there are times a 2nd round will be needed.
