I applied through university. I interviewed at Nationwide (Columbus, OH) in Oct 2020
Interview
I applied online through. I was invited to an interview 2 weeks after that. Mix of behavioral and tech questions with the head of data analytics. They asked me about parallel programming and Git and Python. Then, I was given a take-home project. I had a week to work on it. It was a car accident risk assessment problem based on telematics data, which I did with Python. Then they invited me to the second round interview with 2 people. I was tasked with presenting the take-home project and they asked me some questions about big data analytics with distributed systems like Hadoop. it lasted 1 hour. 3 weeks later I was rejected.
