I applied in October. I recently received the online assessment from the recruiter, asking me to finish it in seven days. It is one hour long and mostly about probability theory, including stochastic processes.
Phone Screen, only problem-solving, no research deep dive or behavior question, one about linear regression, one about three candidates voting problem, an algorithm problem about sorting. It was not so difficult but I was not well prepared so I failed.
Interview questions [1]
Question 1
Three candidates voting problem, linear regression
Started with easy probability questions, and then got hard. There was about 20 questions. Mostly tested Combinatorics and Permutations knowledge and Expectation and Variance stuff. Was a good learning experience.
online coding assessment through hacker rank. included couple easy to medium leetcode style questions. got through all of them in half the time. have not heard back yet. this is to fill up the word count
