Choose a real behavior you can discuss professionally. “I care too much” gives the interviewer little to examine; a concrete example lets you explain what you learned.
Show the change#
Name the behavior, explain one consequence, then describe the action you took. For a fictional example, someone who waited too long to share unfinished work might say they began asking for an early review at a fixed milestone. The result could be better timing of feedback, if their own records support that observation. Do not add a success percentage because the answer sounds stronger with one.
Practise the challenge#
What alerted you? What do you still find difficult? How would a colleague describe the change? Prepare an honest response to each. Use the evidence checklist to separate an observation from a measured result and the answer check to find wording you can simplify. A weakness answer should show a specific improvement process; it does not need to suggest the weakness has disappeared.
