What proportion of automated tests compared to manual ones was used in your last company?

In my last company, the ratio of automated to manual tests was approximately 70% automation and 30% manual testing. Automation was used for regression testing, checking core functionalities, and load testing, which allowed for quick and reliable verification of product stability with each release.

Manual testing was used for verifying new features, UX/UI, and exploratory testing, where flexibility and tester intuition are important.
