I had four one-on-one interviews and a lunch interview.

The first three interviews involved being asked many different technical problems to code.

The lunch interview, which took place at the restaurant, focused on how well I carried myself. For both the lunch interview and the final interview, I was asked a lot of questions about my background, career aspirations, and so on. They seemed focused on assessing whether I would be a cultural fit.

There are four people who want to cross a bridge. They each take 1, 2, 5, and 8 minutes. Only two people can cross at a time, and they take as long as the slowest person. What is the fastest time you can get everyone across?

Then I was asked to write the mathematical equation to determine the trade-off point between each of the two approaches to solving this.
