A few people have responded to this thread w/reactions like "maybe they didn't know how you wanted them to respond". I always clarify if the answer shows confusion.

I wrote this thread to share advice to help people prepare for what might be asked & what employers might expect. https://twitter.com/BecomingDataSci/status/1198351229564440577

(Not to criticize people's answers, but to say how you might consider answering, how to frame your projects to help "sell yourself" to the employer, if you're asked that question)
