Panel Interview includes an industrial psychologist with the team. There are advance materials available and make sure you get them (I didn’t.) Expect the standard STAR format, they will ask general questions and instruct you not to support your answer at that moment. Strengths, weaknesses, how others describe you, how you describe yourself, have at least five of each prepared. Don’t be too frank on weaknesses, they ask but give no grace for being aware of your weaknesses and how you tackle them.
