Google·Product Manager·Onsite - Product Sense / Strategy
May 2026
Google PM-style estimation question about a hypothetical contact lens product that records HD video and syncs to the cloud. One question, pretty open-ended, the kind where you can go in a dozen directions and second-guess yourself the whole time.

“I started with user volume and worked down to per-user storage needs, which felt right, but I kept second-guessing my HD video size estimates mid-answer.” The rest of the author's notes on Product Manager interview at Google, Onsite - Product Sense / Strategy round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
