Two guys would like to meet at a train station and they will arrive at a random time to the station (between 4pm and 5pm) each one will wait 10 minutes for the other what is th eprobability that they will meet? (the brain teasers was classical ones all of them are in the green book). Good luck and don't hesitate to code a little bit of oriented object programming. (it's because of this i didn't get the offer)
Why did you choose this ML model and how does it compare with other models?
Some basic questions about linear algebra, statistics and python programming.
How would you model this using a hierarchical approach? What are the pros of using a hierarchical prior in this case?
1. A rod is divided to n segments randomly, what is the probability that the segments can form a polygon. 2. Randomly choose three points on a circle, what is the probability that they form an acute triangle ? 3. Cannot remember the detailed description, the main issue is to figure out the relation between the cdf/pdf and f(u)=E(max{u-x,0}), with x being the random variable. 4. 2n random numbers are laid in a row. We take turns to take a number. Each time, one can choose from the number on the tail or the head. The one with the bigger summation wins the game. If I go first, can I always win (or tie)?
What is the most challenging part in your project?
Suppose you were to model this process with a hierarchical model. Describe the data generating process, what priors you'd use, and the pros and cons of this approach.

General probabilities / brain teaser questions.
