> Focus on your physical self: make sure you've gotten enough sleep, have food ready to go for lunch, and have breaks between the interviews if possible. If the interviewer asks if you need a minute at the start, and you do - please take it.

This is great advice! I interviewed in 2022 and found that I performed significantly better when well rested. I also found that eating healthy helped during the post-lunch interviews.

Thanks for sharing your experience.
