Tell me about a time you had a conflict with a coworker.
Take a moment.
Say your answer out loud or write it down first — retrieval is what makes it stick. Reveal when you're ready.
Short answer
Pick a real professional disagreement, tell it in STAR form, emphasize understanding their viewpoint, direct respectful communication, and the shared-goal resolution. Show maturity — never badmouth, never claim you were simply right.
Detailed explanation
Interviewers assess emotional maturity: can you disagree productively? Situation/Task set stakes briefly (one or two sentences); Action carries the weight — how YOU initiated the conversation, listened first ('I asked them to walk me through their reasoning'), found common ground, escalated appropriately if needed; Result states the outcome plus relationship status ('we shipped on time and pair more often now'). Choose disagreements about technical approaches or priorities, not personality clashes. Red flags that fail candidates: blaming language, positioning self as sole genius, avoiding conflict entirely ('I've never disagreed' reads as passive or dishonest), going over someone's head as first move. Strong answers show curiosity about the other side before advocacy — 'I realized they were optimizing for X while I worried about Y' — then a concrete collaboration mechanism like writing down tradeoffs or getting data.
Example
S/T: Our lead wanted server-side rendering everywhere; launch was slipping.
A: I asked to understand his concerns first — SEO and first paint. I prototyped hybrid rendering showing SSR for marketing routes, CSR behind auth, shared a benchmark doc rather than arguing verbally.
R: He accepted the hybrid approach, we launched two weeks later than the aggressive date but six weeks earlier than full-SSR would've allowed, and it became our standard architecture.Interview tip
Lead Action with listening verbs ('I asked', 'I learned') before advocacy verbs. Name what you'd do differently if anything — humility lands well.
Common mistakes
- Casting the coworker as the villain.
- Choosing a trivial conflict that shows nothing.
