Recruiter reached me after reviewing my application, then a first interview with hiring managers was scheduled. After that I received a message to inform me that the hiring team wanted to go through a 2nd round interview. It was scheduled one week after. One day before that 2nd interview I was informed it was cancelled because an interviewer was not available.

Recruiter told me they will reach out "shortly" to reschedule. Then radio silence, 2 weeks after received an informal email informing me they decided to move with another candidate. I would expect more professionalism and clearer communication from Mastercard
