That is correct. In the panel interview they're going to be asking left ball questions and more specific technical ones. What they really want is to get a sense that you can do the job and if you'll fit in with the team. If they mentioned any specific skills or knowledge in their job posting you should make sure you are conversant in them at the interview. Don't try to be a technical expert but show up prepared to discuss what they are interested in.
Once the panel interview begins, as they always do, with introductions. Make sure you memorize everyone's name on the panel. Always address the members of the panel by their names. Whenever someone on the panel ask you a question you acknowledge them by name before you answer their question.
Good Luck.
