Why are you leaving your current position?

Reasons for leaving the current job can vary, but for a middle+ level, it's important to show that the decision is conscious and related to professional growth. For example, you can say:

• You want new challenges and tasks that will help develop skills in Golang.
• You have reached a development ceiling in your current project or opportunities for growth are limited.
• You are interested in working with more modern technologies or architectures.
• You desire to work in a team with more experienced colleagues or in a larger company.

It's important to avoid negative comments about your current employer and focus on your motivation to develop.
