I applied through an employee referral. I interviewed at Mastercard (Dublin, Dublin) in July 2022
Interview
Really straight forward. First a code challenge. As I was applying for junior position was to develop a method to search array inside an array. The answer came out on the same day and I was booked to do the screening. The screening was booked for my convenient data (3 days after) and it took 1h. We talked about Java concepts (basic), SQL(basic answer queries statements), gRPC and OOSE
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
I applied online. I interviewed at Mastercard (Lisbon, Lisbon District)
Interview
The interview was friendly, intuitive and made me think about what I want. Everyone was friendly and welcoming and ready to help. It was 3 phases, questions, after that was the technical and the last was a personal interview.
