Round 1

1. Warm up: Find the first no repeating character in a given string
2. LLD + HLD discussion on a url shortener system

Round 2

1. Short discussion on a past work project
2. HLD + LLD of a rate limiter
3. Some questions on Kafka, what would you do when when you’re on call and find issue like higher latency in an API etc.

Verdict

Rejected. Seemed better fit for SDE 2, didn't move forward.
