At this stage in the interview process, you already know that the candidate is generally well-qualified for the role, so it's time to dig further into culture fit and work style. See if you can identify what motivates a candidate, what drew them to your company and how they work on a team, amongst other questions.
The Group Panel
By meeting with a variety of people, candidates get a comprehensive picture of the culture and the job itself, and team members get a strong sense of the contribution the job seeker will make as an employee. Make sure you prepare interviewers with the job description and the candidate's resume. Also, don't forget to identify a panel leader, and assign roles to each interviewer based on job function and/or expertise.
The Candidate Presentation
Team members will get a sense of contribution, skills and personality during a job seeker's presentation. However, you will need to make sure to be specific about the presentation topic to the candidate, and also determine objectives for evaluation of the presenter with the team. And don't forget to solicit feedback via a scorecard or a post-panel debrief.
