Group interviews serve a beneficial purpose in enabling the employer to meet and interview a group of candidates one by one.
Doing so saves time. It also makes it easier to fill multiple positions when you have a large group to interview in a couple of hours.
Here are my suggestions on how you can run a group interview effectively:
Have a set structure for what will occur on the day and stick to it. You may decide to spend the first 10 minutes introducing yourself, then conduct a role-playing game to see how the candidates work together, after which you conduct one-on-one interviews.
Be prepared to adjust accordingly and adapt as the day unfolds. Further on to tip #1, be mindful that not all the candidates may turn up. Instead of 10 candidates turning up on the day, only three arrived. In such an instance, you've got to be able to change it up and review what you had planned for the day.
Make it light-hearted and relaxed. It's crucial to ensure that the candidates feel at ease and comfortable.
Remind the candidates the day before about their interview and explain what they should expect to happen. Make it clear to the candidates that they are not all vying for one job. If they feel that way and think that, it's unlikely they'll show up.
Ask the candidates how they feel, their thoughts, and if they have any questions. Further to tip #4, it's crucial that candidates feel at ease and not disturbed by seeing the other candidates in attendance.
