There were three interviews in total: two technical rounds and one final team-fit/behavioral round.
The technical interviews were fairly demanding and covered both implementation and system design topics. The first focused on writing a Java in-memory load balancer with attention to validation, edge cases, and TDD. The second involved implementing a concurrent transaction operation between two bank accounts with an emphasis on avoiding deadlocks, followed by discussion of SQL locking strategies, parallel programming, distributed systems, CQRS, and DDD.
The final interview was a team-fit round centered around behavioral questions and past experience. I was expected to explain projects in detail, including technical decisions, metrics, and outcomes.
The biggest issue with the process was the communication. Response times were consistently slow, and I had to follow up after each stage to get updates. I communicated clearly that I was in the final stages with another company and later that I had received a competing offer, but this did not seem to meaningfully affect the pace of communication.
After completing the final interview, I never received any update despite following up, which made the overall experience feel disrespectful to the time and preparation the process required.
