The Cybersource interview process goes through a technical ability test online. This test is done through a portal where some pre-set questions are asked. There were two following interviews, one technical and one business oriented.
Two rounds of interviews remotely + a technical challenge. One of the more behavioral, the other focusing on the technical side - Java, oop, payments word, technical stack.
Went through my CV asking about key points, make sure you can support it with examples.
