Process

Two guys interviewed me. The interview was about concurrency. They gave a task from HackerRank and asked for more details about my task during the interview.

The task was about a payment system. You should prevent fraud cases and implement two methods. One of them was payment, and the other was getCardCountAtLastTenSeconds.
