Luxoft Devops Engineer interview questions

I applied online, As soon as i applied the HR called me saying your resume looks very nice as you have a lot of experience on coding.. etc., She asked my salary expectation, My work status etc., everything went well with the HR. She then scheduled an interview for next week. But the day before, she said the guy who was suppose to interview you is on tour so we will have to reschedule. Then she moved it to 1 week after. She literally scheduled for 5 times. I was very patient throughout the process. Finally she scheduled with a confirmation from the interviewer. The position basically for one of their clients and was regarding automating the tasks we perform on clouds using cloud API, python etc with a knowledge of cloud technologies like aws, azure, vmware and maily openstack. But the guy who interviewed me did not even ask me questions on automation but he asked me on networking with kubernetes, jenkins pipeline etc.. Throughout the whole interview i was very confused thinking when is he going to test me on python and cloud api. Unfortunately he never even asked a single question on python, openstack, vmware, azure etc.. The interview was about 30 mins. I answered almost all the questions. But next day i asked the HR if she got any feedback.. She replied saying.. They did receive feedback from him and the team decided they will move with a different person. What a waste of time. But after reading many reviews on glassdoor i am glad they didn't offer me a position. Please don't waste your time with these people.
