Case Study: The 'We vs. I' Trap That Rejects Senior International Engineers in US Interviews
Fact-Check Source: Verified against FAANG / Seattle Tech Bar-Raiser Behavioral Rubrics (STAR Method).
Director: What did you do when the database overloaded? Candidate: Our team had a big problem with the database, so we decided to add Redis and we fixed it before the sale.
Director: What did you do when the database overloaded? Candidate: Forty-eight hours before Black Friday, our primary Postgres cluster hit ninety-eight percent CPU. While the team debated a three-week schema rewrite, I profiled our slow-query log, isolated three N-plus-one catalog queries, and implemented a Redis read-through cache in two days. That reduced database CPU by sixty-eight percent and supported four-X peak traffic with zero downtime.
