You have four tests that benchmark how much power we expect to draw from the servers in a rack: a (5 minutes), b (10 minutes), c (15 minutes) and d (30 minutes) that are conducted sequentially over the course of an hour on 10 servers in a rack. To my great surprise, i was selected for an interview with amazon for an applied scientist position. i’ve been all over places like leetcode, but was wondering if anyone here has any advice as well.

Data science interview questions for faang are designed to assess not only technical proficiency but also a candidate’s ability to solve complex, real world problems using data driven approaches. Cross validation is a technique for assessing how the results of a statistical analysis will generalize to an independent data set. it is mainly used in settings where the goal is prediction, and one wants to estimate how accurately a predictive model will perform in practice. Prepare for your faang data engineer interview questions and answers with guide and practice data modeling, etl processes, and more to ace your interview. Cross validation is a statistical technique used to evaluate the performance of a machine learning model. it involves partitioning the dataset into multiple subsets or “folds” and then training. This is quite an interesting question, since it involves probability pertaining to overlapping random sets. i'm going to solve this for a more general problem where we have $k$ servers.
