A recruiter reached out to me by mail and although I wasn't searching for a job, it was curious to hear what the role is about. Process was very good, nice people and let you feel they are with you. The recruiter gave me the option to speak with Data Engineer, and I have asked all my questions. I was too stressed out during the first half of the interview that I couldn't think at all and unfortunately did not passed it. It's OK, I probably will not hire myself in that case.
