Mastercard Senior Software Engineer interview questions

Applied to on-line job listing. Within 2 weeks I was contacted by HR for a telephone screening interview. This was followed by telephone interview, followed by in-person interview on site.

I have online hacker rank test and then was invited for face to face interview at MasterCard office. The onsite interview feedback was positive. But they didn't even communicate any further information regarding the interview feeback. This type of unprofessional behaviour was not expected from Mastercard, Singapore.
