o9 Solutions Devops Engineer interview questions

I applied through agency. The whole process took 3 weeks. First, there is an HR interview. He did not describe or do some introduction about the company at the first place, and asked me do I know anything about them. The purpose of this round is just testing my Japanese skill. Second, a hackerRank which is quite easy for me but I feel that they translate the questions to English from some kind of language, the translation is not smooth so it affects a little bit to my experience. But I still passed with flying colors Third, I was told by agency this one is a Technical Round. But the schedule for this interview is just 30 minutes. I was interviewed by a Korean member. He made me reschedule the interview 2 times, and even came late for more than 10 minutes. But there is no technical questions, no client-facing experience. The moment I said I do not have hands on experience with Ansible, he just stopped asking questions. The interview was ended in awkward between us. Since I wrote everything in my resume, they should decline my application the moment they saw that I did not write Ansible in my techstack. The whole process is just unprofessional for both this company and the agency. Of course one day later, I was failed because of techstack mismatch. They are just looking for a guy who knows how to write Ansible :) Totally time-consuming for this kind of company.
