CRED Interview Experience | SDE-1 | Never Got proper Closure
Summary
The candidate had a positive technical interview experience with CRED for an SDE-1 role, but the process ended without a clear outcome due to poor communication from HR.
Full Experience
I participated in a three-round interview process for the SDE-1 role at CRED. The first round was a machine coding challenge where I had to extend an existing codebase to calculate latency, throughput, and error rate metrics within a timestamp range. The solution needed to be clean, correct, and extensible for future metrics like p90 latency. The second round was a system design discussion about creating an InDrive-like platform with specific constraints on pricing and negotiation. The technical rounds were well-designed and positive, but the HR round was never scheduled, and the hiring process was abruptly closed. I was later contacted by different HR representatives but received no further communication.
Interview Questions (2)
Extend an existing codebase to compute and display the following metrics within a given timestamp range, based on existing event data: latency, throughput, and error rate. The solution must be extensible for future metrics such as p90 latency.
Design a system similar to an InDrive platform where only drivers can list their prices, and customers cannot negotiate or counter-offer. Discuss core components such as driver discovery, pricing flow, matching logic, and scalability considerations.
