During the final interview, I was asked about how a Redis HA (High Availability) Cluster infrastructure behaves when connections between certain nodes are interrupted—specifically, how the HA environment adapts and what happens to data consistency in such a scenario. I did my best to share my assumptions, but they turned out to be incorrect. When I admitted that I didn’t know the answer, I was encouraged to imagine and "think logically" through the situation. This led to a back-and-forth where I was clearly out of my depth due to my lack of hands-on experience with Redis. I want to emphasize that I had been transparent from the beginning about not having prior experience with Redis and that I would require proper training and onboarding. Despite this, the interview focused heavily on advanced Redis-specific scenarios, which made it difficult to demonstrate my potential or skills in a fair context.
