Affirm Quantitative Associate interview questions

Overall it was a positive experience. It took about 3 weeks. The problem was one of their rounds was for a technical write-up, and they didn't give a lot of specifics. They left it intentionally vague. I decided to do my write up in a more academic style rather than a practical style and because of that they decided to reject me. I would have appreciated it if they clarified specifically what they wanted before hand.
