OYO interview questions

First Round - On a call: Briefly interviewed on my previous projects and roles. Second Round: Was given a case study on their dummy data set. Had to solve it in 24-48 Hours. It was based on R, Python and SQL along with couple statistics questions. It was based on descriptive statistics though. Final Round: Was asked to visit the head office based in gurgaon, and went through three rounds of interview. I was asked technical questions on R, Machine Learning concepts and my previous project experiences. Then out of never-ending rounds was the final round of interview with the Analytics practice head. Everything seemed fine, but I probably screwed one SQL question and wasn't offered.

Very Balanced Sets of Questions and they touched the all the concepts of fundamentals in computer science. You have to be very good at Fundamentals like OS, DBMS, Coding, Computer Networks etc
