I applied online. I interviewed at Mastercard (San Francisco, CA) in Jan 2019
Interview
First step is a 30 minute phone interview with the hiring manager about your resume/background and an online assessment, if you pass that then you go to final onsite interview
The process was fast with 3 rounds of interviews. Online assessment, on-site interview followed by a round with the hiring manager. Medium level questions online and hard level leetcode question on-site.
Fairly simple interview question that required knowledge of basic data structures. I could use a programming language of my choice. The interviewer then asked some additional questions and requested several solution extensions
