I applied online. The process took 1 week. I interviewed at Mastercard (New York, NY) in Aug 2022
Interview
Very easygoing and nice interviewers.
There were two interviews, a technical and a behavioral, 45 min each.
For technical make sure to study OOP concepts and basic data structures and algorithms, they just want to know how you think.
For behavioral, it is like any other company. Basic questions like, introduce yourself.
