Entrevista
Interviewed in person and over the phone. First interview was mental math and probability/expected value questions.
First probability question: two players have an A, K and Q. You simultaneously flip over one card at a time. What is the probability of having at least one match?
Second: Take a 3x3 cube and dip it in paint. Break it into 27 1x1 cubes. Pick one at random and roll it. What is the probability of having no painted sides shown?
Third: If the current date is in the format mmddyyyy, what is the next time that all 8 digits will be unique?
Second interview was one question about an expected value dice game
