algorithm complexity
Algorithms, data structures and SQL on whiteboard About 6 hours of 1:1 technical interviews with 5+ people in various domains (networking, database, programming, hardware).
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.
