Brain teaser: There are 3 jars full of yellow jellybeans. One jar is lemon, one jar is banana, and one is a mixture. The only way to differentiate between the two flavors would be to taste one. They are initially labeled correctly, but someone goes and switches the labels such that they are all wrong. How many jellybeans will you have to eat to determine which jar is which?

I had two physics questions in the first one, both mechanics. I then got a chemistry question. In the second one I had a graph sketching question with some follow up on the behaviour of the derivative of the function and its roots. I then got another problem related to chemistry. And then I got another physics question. I was not asked anything non-technical.
