Mastercard had two interviews that asked questions about how to test a webpage that they pulled up on a PowerPoint. Was a fine interview though the interviewer seemed to be looking for overly specific answers. Iw as asked the same question in both rounds which I thought was fairly odd.

it was one technical interview, and then followed with one onsite (technical and behavioral). both technical interviews were oop type questions (not leetcode style). behavioral consisted of the standard questions.
