Start with the shortest accurate cause
Name what changed without building a defense speech: the role ended, the scope changed, a practical constraint no longer worked, or a chapter was complete. Use the description that matches your records and references. If the employment ended involuntarily, say so in calm factual language rather than presenting it as your choice.
Remove blame without removing the truth
Leave out judgments about a former employer, manager, or coworker. Also leave out confidential events and guesses about another person’s motives. A neutral answer is not a rewritten history; it is a bounded account of the cause, any part you owned, and the work condition you are choosing next.
Add a forward constraint and one proof line
Name something this role actually offers: a type of problem, scope, schedule, location, or responsibility. Then add one short action or result that shows why the move is credible. The cause is not a STAR story, so stop after the proof line and let the interviewer choose the follow-up.
Prepare the consistency check
Compare the sentence with your application, resume dates, and what a reference can factually confirm. Prepare to explain your responsibility and what changed without inventing another person’s assessment. If the transition created a visible gap, use the separate employment-gap guide for the time between roles.
