The interview process was quite casual. Did not face any particular difficult questions
Signed a non disclosure agreement.
algorithm complexity
What is correlation? What is covariance? Made a graph that the correlation is equal to 1 and -1.
Questions involved familiarity with Linear Regression (it helps to be topically familiar with either iterative LR, PCA, or orthogonal matching pursuit), Minimal Mean Squared Error, probability theory (binomial random variables, gaussian distributions, markov chains, properties of expected value/variance, hypothesis testing), and basic coding (a very trivial programming question when compared to SWE interviews).
Ridge regularization.
What is the angle between the minute hand and the hour hand at 12:15?
