Analytics Intern Interview Questions

13,100 analytics intern interview questions shared by candidates

We have two types of reviewers: careful reviewer (80% of reviewers) and lazy reviewers (20% of reviewers). Careful reviewers rate a post positive 60% of time and negative 40% of time). Lazy reviewers however rate a post positive 100% of time. A) what is the probability that a random ad is reviewed positively? B) If an ad gets a negative review, what is the probability that it's reviewed by a lazy reviewer? C) If 3 ads are reviewed positively in a row, what is the probability that they are reviewed by a lazy reviewer? D) Some as above with n positively reviewed ads in a row. What happens when n goes to infinity? E) If we have very few labeled data, how can we build a model to distinguish between careful and lazy reviewers?

You are dealing cards out to four players. The phone rings, and you answer it. You come back to dealing, but you can't remember where you left off. How do you continue dealing so that the outcome of deal is that same that it would be normally? You can not count or touch the dealt cards.
