Hi both! Interview over! I had way overprepared for this so I did end up blanking quite a few times. But the team was really understanding. It was the program director, and three other professors from the archaeo department. They were very kind. First they introduced themselves, then they asked me about my project straight up. I was expecting an introduction from myself, or provide background details etc but they just wanted to know about the project. Then after explaining it, I had a few questions about whether there is something I look forward to studying theory/methodology wise. I said I can't be specific since I'm applying to the program to gain knowledge about it, so I ended up listing courses I am interested in taking. After that, they asked "why archaeology, and what faculty are you looking forward to working with?". Finally, they asked whether I had any questions.
I blanked a lot, and looked at my notes and they did not mind at all. They were encouraging and carried the conversation. I am hoping for a positive response! Hope this helps! It's okay to be nervous, just tell them that upfront. There's only so much you can do in 20 minutes.
