Five to Six interviews altogether for this role. Such a waste of time with Old schoolers. First Interview:- HR round Second Interview: All agile , non-technical boring questions, seems like an exam or viva after taking an Agile scrum course. Such a waste of an hour. Third Interview: (SE Tech SME) 1. Explain your current project. 2. What are 12 factors? 3. Mostly question Related to Ecommerce website questions with real-time use cases. 4. Questions related to Authentication and authorisation. 5. What are improvement done for Garbage collection in Java 8 6. Spring bean-related question 7. Availability and Kafka-related questions 8. Java stream api. Question on REST api design practices. Fourth Interview: (SE Interview Manager ) - Small coding test during interview. - Went through my CV and recent projects etc - Asked about Product from an API and display perspectives. Fifth Interview: (tech Interview) - Coding test: Find Median number if your data is placed on several different servers like server 1, server 2, server 3, server 4. How would you find the median then? What if the data is so huge and won't fit in your ram? Its a tricky question and standard complex problem to be asked in an interview. - Followed by some system design interview questions. Sixth Interview: (SE Bar Raiser) - Another complex coding test to Board search with given word, count. (Anagram problem in a 2D table) - Followed by some OOP questions, and system design questions again. - Bar Raiser interview is always non-technical and more of personallity and behavioural round. But they end up with the technical test and system design. I guess they messed up there.

I interviewed with Mastercard several times across 2025 and 2026. Unfortunately, the overall process was not professional and the candidate experience was disappointing. Multiple interviewers either did not show up or cancelled at very late notice without proper warning or communication. As a candidate, you spend significant time preparing and arranging your schedule, so repeated last-minute changes leave a very negative impression. This year they introduced the Karat interview process, and I have to say that part was much more professional and organized compared to previous experiences. At least the first round felt structured and respectful of the candidate’s time. However, beyond that stage, the overall interview coordination still felt disorganized and inconsistent. I hope they improve communication, scheduling discipline, and respect for candidates throughout the full hiring process.
