I first received a phone call from the team lead. He asked some general interview questions and then some easy technical questions. Then later, he emailed, and I received the job offer.

I applied with an HR. After the first screen call I got a list of questions about my work experience on e-mail. The second call was from a manager at SSH. He sounded grim and unwilling to talk. We talked mainly about security, TLS, PKC, and he assured me that just basic knowledge of security is needed in this position (which I do posess). He told me to do the coding assingment. After I did the coding assingment and waited more that a week for the feedback, I got an email with these words: "the coding task is ok, but you lack the security knowledge, so rejected". I am still confused, why they decided what I lack and what I don't, since no evaluation of my skills was performed and I was told that no strong security skills were needed at this position. So, for me it was a huge waste of hope and time.
