OA (codesignal) --> powerday (case interview, technical, and behavioral). Case interview was on cc processing with diff rules for different cc companies, with questions on business/customer benefit, answering test cases according to rules, and fixing code bugs according to rules. They walk you through each step and LC easy with some business context. Just talk out loud and check with the interviewer often. Technical interview was fraud detection for credit and debit transactions with OOP (use classes). This was similarly step by step and LC easy. Behavioral was 1) Tell me about a time you challenged a status quo. 2) Tell me about a time you collaborated with a teammate. 3) Tell me about a time where you had to learn something new (focused on the results). One hour each interview was allocated but I ended up finishing early for all and used the rest of the time to ask questions. They filled the Feb Cohort and gave me an offer for Aug.
