Has there been a time when the result of your work did not satisfy your supervisor?

Yes, such situations happen to every professional. It is important how to react to them:

• Analyze the reasons why the result did not satisfy the manager — perhaps there were misunderstandings of the requirements or expectations.
• Discuss specific points for improvement with the manager.
• Make adjustments and improve the quality of work.

For example, in one project, I implemented a functionality that technically worked correctly but did not match the business logic expected by the manager. After discussion, I refined the solution, which increased satisfaction and product quality.

Such situations help grow professionally and better understand business requirements.
