Mastercard Software Developer interview questions

I interviewed in December 2023,The interview process is one day long, consisting of three rounds conducted consecutively with swift transitions. However, the main issue lies with the Dublin HR system. The talent acquisition team is unresponsive, failing to provide feedback even in cases of rejection. It is baffling that candidates are ghosted without any communication. HR representative, is particularly lacking in fulfilling basic HR duties. Emails and calls go unanswered, leaving candidates in the dark about their application status. While I hesitate to name individuals, the same experience occurred with a friend of mine. It is disappointing that a reputable company like Mastercard struggles to hire competent HR staff.
