Behavioral question
Tell me about a conflict with a coworker
They want a disagreement about the work, not a personality feud. Show that you understood the other person’s constraint, said the hard thing directly, and left a decision someone can point at. Stories that end with “we agreed to disagree” usually mean the conflict is still open.

Which sentence is which
In August 2023 the platform team and I were stuck on a migration. I was responsible for a plan both sides could live with. I scheduled a 45-minute working session and wrote the cut line on a whiteboard: which three endpoints had to move, and which four could wait. I then asked him to mark the risks he would not accept, and I cut two endpoints from the launch. I wrote the deferred endpoints into the launch note so sales could tell the customer what was coming in the following release. The result was the launch shipping on the original Thursday with those two endpoints deferred, and zero rollback that month. Support tickets about the old API fell from 22 a week to 9. My coworker wanted to freeze features for six weeks, and the product team had a launch date.
Why this example holds up
You name the other person’s real constraint (risk), you do something visible (the cut line), and you give up scope. That is more believable than “I convinced him I was right.”
How to answer “Tell me about a conflict with a coworker” with STAR
- Situation. Set the scene in one or two sentences: when it was and what was already wrong. For example: In August 2023 the platform team and I were stuck on a migration.
- Task. Say what you personally owned. For example: I was responsible for a plan both sides could live with.
- Action. Say what you did, in order, with I. For example: I then asked him to mark the risks he would not accept, and I cut two endpoints from the launch.
- Result. End on the change, with a number you can defend. For example: The result was the launch shipping on the original Thursday with those two endpoints deferred, and zero rollback that month.
Mistakes on this question
- Describing the coworker as difficult, lazy, or political. The interviewer hears that you will talk about them the same way.
- Using we for every sentence so it is unclear what you said in the room.
- No decision at the end. Conflict stories need a call that was made.
How to practice it
Say the other person’s concern in one sentence before you say your own. If you cannot, you are still arguing, not recounting.
FAQ
Can I use a conflict with my manager for this question?
Use a peer if you have one. Save the manager story for “tell me about a time you disagreed with your manager,” which asks about power, not just taste.
What if the conflict never fully resolved?
Say what you agreed to try, for how long, and what you measured. An open feud with no experiment is a weak ending.
