yikes... I am an HR Director and I must say that not many companies use behavioral interviewing that I know of anymore! Often times this type of interviewing can lead to violations of discrimination laws, by the interviewer making inappropriate comments... and frankly most people see this as an ineffective system of interviewing with the exception of a handful of situations where it is practical to see the results of serious stress on an employee... such as those being interviewed for law enforcement positions...

the VP sounds like he had a separate agenda... perhaps he already found a candidate that he liked and made it difficult for others intentionally...

glad you found out now... best wishes in the job search.
