UNC Health Care uses Hiring for Excellence behavioral based interviewing. Target Selections by DDI. Either one person or a panel asks specific behavioral based interviewing questions. For instance, tell me about a time when...what was the end result? Usually a background of the job is given and then questions after words. Lately, I have been having panel interviews instead of one-on-one. The process is good, but it takes a long time for the interviewers to score the interviews and then the interviewee has to wait a long time.
