After applying, I was contacted rather quickly via mail by the HR. The HR scheduled an interview with the technical lead. The 45 minutes long interview was about my previous working experience with the devops technologies. The atmosphere was very pleasant and I could also freely ask questions about the company and how they work. On a bad side, I've never heard from them again, even though I was promised a feedback (positive or negative). Even after writing to the HR to ask for the feedback, I didn't receive any response.
