Reasons for leaving current and previous jobs.

Reasons for leaving current and previous jobs can vary, but for a senior QA, it is important to emphasize professional motives:

• Desire for professional growth and mastering new technologies.
• Looking for more interesting and challenging projects.
• Dissatisfaction with organizational processes or company culture.
• Limited opportunities for career development.

For example, you could say: "I have reached a certain ceiling in my current company and want to develop in the direction of test automation using modern tools and methodologies."
