I recently applied to Phonepe for SDE 2 profile, and gave the first round which was the machine coding round. It was hosted on Code Signal and I had to code the solution from scratch. Post the design round, there was a 30 minute discussion. Would love to learn from expereinced design engineers as to how they would go about coding this problem, I was able to write basic CRUD methods for this problem statement but beyond that I got a little lost. Please help, I am new to design interviews and would appreciate mentorship and guidance from expereinced people.
