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)
Metrics Calculation in Event Data
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.
InDrive-like Platform System Design
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.
