Have you had experience with A/B testing?

Yes, I have experience working with A/B tests. Usually, I participated in formulating hypotheses, defining metrics to evaluate the effectiveness of changes, and analyzing the results. For example, for a web application, we tested different designs for the "Buy" button: changing the color and text to increase conversion. Users were randomly divided into two groups, and the behavioral differences were measured based on the results. This approach helps make data-driven decisions rather than relying on intuition.
