Had one video interview where I had to talk about a previous project I'd done and ideas I had for projects to work on during the summer with them. The ideas didn't necessarily have to be things I could do or would do, but were used to see my thought process. I was expected to answer technical questions about my previous project (how the models work, why I chose certain tools, etc)

I had a phone screen with a recruiter than a one-hour video technical interview with the lead data scientist. I did not move forward after the tech screen. The recruiter was very unresponsive and did not provide that information. She just ignored my emails. Some of the questions during the tech screen were: (1) Suppose Buzzfeed has a dynamic news flash where initially there are lots of hits and it diminishes. How do you sustain the rate of hits? How do you measure it? Design an experiment. (2) Suppose there is a 'share' button on the top and bottom of the page. What metric do you use to measure where the button should be? (3) Some SQL questions, (4) Create a function to compute the Jaccard similarity scores for all of the other articles with respect to all pairs
