The technical interview started with some peculiar requirements. In an email, they stated: "Please ensure you can share your screen, have a strong Wi-Fi connection, a laptop, and a working camera and headset with a microphone."

However, what if I had a PC with an RJ45 connector instead of a laptop and Wi-Fi? Ultimately, this was a minor concern.

They suggested practicing on HackerRank to prepare for the interview. HackerRank is primarily algorithmic, whereas their task involved the simple implementation of a "load balancer registry" that needed to store no more than n instances—a fairly straightforward solution. After implementation, candidates were asked to write unit tests for every scenario. For this, a Maven JUnit dependency would have been necessary. Subsequently, I was questioned about thread safety, which was not an initial requirement.

Following this stage, I received an email stating, "...I hope that the feedback I was able to give you helped you to understand what we were looking for."

The email originated from a no-reply address, and no actual feedback was provided.

Implement a Load Balancer Registry, which is a database of service instances and their locations.
