Mastercard Sr. Software Engineer interview questions

Total waste of time.... Got a call from MasterCard then after couple of days they shared one test link... After test, need to followup for a week or two then got positive feedback for it. After this they took 2 weeks to schedule first technical... That also I have cleared and then again 3 weeks to schedule next round... This round was also positive, in interview last section I was asked about expected salary how can I commute to office, about work from home almost everything HR asked before joining... But since then it's been 4th week and I am still waiting for feedback... Everytime I call or drop an email they don't bother to answer the calls or emails.... So unprofessional totally not expected from MasterCard.

Initial interview with the HR. Two rounds technical interview. I just had the first round, I was asked to go for the second one but I declined as I gave precedence to other positions I had applied for.
