HackerRank Devops Engineer interview questions

I interviewed for the position of DevOps Engineer and the process was about 2 weeks long. First think which I must mention, even though Hackerrank is working towards improving the interview process, their own HR and recruitment process is a crass. I went through 8 rounds and they even organised culture fit for me two times. I mean if you know if somebody is not going to be a culture-fit for your company, why waste your own and theirs time. It was really a bad experience and never expected this from Hackerrank
