Product matching case: design the approach and say what could be improved in the current model
Asked in the HM phone screen stage. The wording was paraphrased from the author and the full prompt was only partially visible because the source was points-walled.
Explain how you would investigate the existing product matching model before proposing changes. Cover the data, candidate generation, matching model, serving architecture, evaluation, and likely failure modes. State the assumptions or clarifying questions you need rather than inventing product or scale details.
