Don’t be afraid of a group interview. As daunting as it might sound, think of it as a one-on-one to lessen any fears. Just like for any interview, practice beforehand, find out as much about the hospital/group beforehand and remember exactly what is on your curriculum vitae as otherwise what you say will be taken into question. In the case of a group interview, practice working a room. Group dynamics is like team dynamics.
You may want to introduce yourself when you walk into the room. This shows that you are able to lead and have initiative. Just like in a one-on-one interview, listen to what is being said and not said. Use these as clues to how and what you will respond. Also, just like in a one-on-one interview, be assertive, not aggressive; be calm and discuss your skills and how they will benefit the group. If one person in the group interview isn’t engaged, try to draw them into the conversation. Don’t get intimidated by the group to the point that you’re afraid to ask questions.
Don’t try to be someone you’re not. The group is trying to figure out how you will fit in. You want them to know what you do best and enjoy the most.
