Round 3: HLD [On-Site Mumbai] – 27th April, 2024
Travel: Flight tickets were arranged.
Initially, they inquired about the technologies I have worked on to decide the system design question.
Questions included:
Internal implementation of Redis lists
CDC with Debezium
Which isolation level is used in your databases
After about 10 minutes, they asked me to design a system for sending lineup notifications to Dream11 users, which are sent 30 minutes before the start of a match.
The system needed to be elastic, capable of handling scenarios where only 1000 users have joined a contest or even millions.
Input was from two Kafka streams: one for users joining the contest and the other for the contest lineup info.
Proposed Solution: Redis + Spark
Other interviewees were asked to design systems like the Dream11 leaderboard and Dream11 digital wallet.
Result: Positive
