In the first round it was mostly behavioural and questions regarding when did you demonstrate leadership, scenario based questions with examples in your current project/org were asked.
In the second round it was again a bit of the same and in the beginning mostly questions related to testing, automation with a focus on java, api testing were asked and then it was again behavioural/scenario based questions.
Third round was more technical - an easy LC question based on arrays was asked. Grilled on API design and testcases - how would you design an ecommerce API, what all you will test, how will you test it etc. And again behavioural questions were part of this round too. Some of the same scenario based questions were asked in the previous round as well
