What is the probability of an even number of heads when flipping n coins?
They asked us not to share.
A questionnaire, a takehome challenge and lots of stats questions. Know well linear regression and logistic regression. For instance, they ask you to derive the OLS formula on the board.
The brainteaser was a variation of the 100 coins and 5 pirates. There were 6 pirates instead. So the premise is that there are 6 pirates and you are the captain. You must divide the coins. If 50% of the people rebel against your allocation, they kill you and the process starts again. What is the optimal allocation?
Interview 1, Q1: Find the eigenvalues and eigenvectors in a 3x3 matrix. Q2. Explain how you would find the mean value in an array. What is the time complexity of a sort function, and explain why.
How many N in [100,400] s.t. N^N is perfect square

Suppose you are given a cube, you break the cube in 3X3X3 pieces. However, before doing so, all 6 faces of the cube were colored green. All the other faces not colored green will be white after breaking it up. You randomly pick a small cube and see one face which is green. What is the probability that the cube is an edge cube?
