Have you ever invested in a solution that was not accepted? How did you handle it?

Yes, I have had such experience. It is important to understand that not always the decision you invested in is accepted by the team or management — this is part of the process.

I try to:

• Analyze the reasons for rejection, understand what exactly was unsatisfactory.
• Get feedback and, if possible, improve or adapt the solution.
• View rejection as an opportunity to improve my communication and argumentation skills.
• Not take rejection personally, but use the experience for growth.

For example, I proposed a new approach to a component, but the team chose a different path. I supported the decision and later suggested improvements within the chosen option, which increased trust and collaboration.
