Real, anonymous reports from people who interviewed for Software Engineer at Mastercard, newest first and distilled into what to expect across the loop.
After a recruiter update, I moved through four rounds for a Software Engineer II role at Mastercard. The conversations started technical and got more focused on problem-solving as the process went on, ending with a final discussion with technical leadership. The interviewers felt knowledgeable and the technical discussions were genuinely engaging, so the actual interview portion left me feeling fairly positive about how it went.
My interview experience included a segment where I was asked networking and security questions that I wasn’t familiar with. The questioning felt erratic rather than structured—there didn’t seem to be a defined set of questions, and it came across like the interviewer was generating prompts on the fly. The whole moment made it hard to know whether I’d missed the target because of gaps in my knowledge or because the pace and content kept shifting.
