I interviewed at Mastercard on December 9th. The process started with an introduction and questions about cultural differences between Nepal and India, followed by a discussion of my projects and prior experience in testing. The interviewer, Deepak Mishra, asked about functional and non-functional testing, Mastercard's products and services, and situational questions like performing testing without a requirement document. I also highlighted my knowledge of tools like JMeter, Splunk, and Jira. The interview concluded with a discussion about the team structure. Overall, it was a well-structured and engaging interview.
