Pregunta 1
How would you design a client facing microservice for file procesing using AWS Lambda
This took a bit longer than expected, stretching over several weeks. The technical rounds were intense, featuring an LRU cache implementation and a problem on detecting duplicate transactions within a 60-second window. I was nervous at first, but it clicked for me when I realized I had practiced a similar approach on PracHub just days before. Unfortunately, I didn’t receive an offer in the end, but the experience was a solid learning opportunity. The behavioral questions felt straightforward, so I wish I had made a stronger impression in the technical segments.

Entrevista
Recruiter reached out after I interviewed. We scheduled a call and I received Coder Signal. I think it was proctored, but I don't remember clearly. 90 mins and 4 qs, 2 of which were regular algos. Another one was a very long system design question. I think it was to implement a cloud system storage. Recruiter forgot our scheduled call afterwards and I didn't bother reminding her.
