First recruiter call, then a codeSignal challenge with 4 questions ranging from easy to medium. I only attempted 2 questions and was invited to “PowerDay”. The virtual on-site consists of 4 interviews - case interviews which is a code question in Java which you have to talk through with the interviewer to solve. - systems design for a credit card payment system - behavioural interview, 3 “tell me a time…” questions - technical challenge about counting prime numbers from 0 to n. The recruiter was disconnected from the process through out, was late to every phone call meeting, did not apologize but said we have to recruit 300 candidates, interviews run long. As other interviewees have mentioned, communication is a huge barrier during the power day interviews. I struggled to understand the accent of the interviewers and asked them to repeat the questions several times. Please take a notepad and write what you hear, then repeat to ensure you understand.
