The process was awful, the HR recruiter never tell me feedback and the Technical interview one Colombian only ask me question about theory in microservices, patterns, etc. Some question I did not know then I was rejected. But They didn't mind about the experience or my level in the algorithm, maybe that was the feedback, but HR didn't tell me to improve in the future, or Etc.
In addition, the interviewer is not more experience than me in Software Development, I researched on LinkedIn. I don't recommend pass the process here
