“I started with the brute force scan, which is just iterating every cell, grouping by block index (row/3, col/3), tracking the min per block, then comparing across blocks.” The rest of the author's notes on Software Engineer interview at Google, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I started with the data ingestion side, talking through polling vs webhooks and how often the USDA dataset actually updates (not that often, so a scheduled batch pull made more sense than anything real-time).” The rest of the author's notes on Software Engineer interview at Google, Onsite - System Design / Architecture round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“This one took me a minute to get into because there are so many directions you can go.” The rest of the author's notes on Software Engineer interview at Google, Onsite - Behavioral / Leadership round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.

“I jumped straight into crawling and ingestion and kind of forgot to clarify what 'search' even meant here.” The rest of the author's notes on Software Engineer interview at Google, Onsite - System Design / Architecture round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
