It was a pure fake interview process. The first interview was a general one. Then they asked to create a presentation of the architecture for the given scenario. I used the architecture recently published on microsoft site. After that they had a "tech" interview without a real tech question but about my experience and the used architecture made as a test task. During the interview, the interviewers were happy with the answers but 2 weeks after that, they sent me a rejection letter saying that technologies and approach used in the test task is not modern! The architecture was published by Microsoft 4 months earlier, it uses modern Azure cloud platform, modern Cosmos Db, Azure Traffic Manager, App gateway, Load balancer either directly or as docker containers orchestrated by k8s and services represented as REST micro-services. And they were not capable to make up anything after I sent them the link to MS site with the "unmodern" architecture. They also wrote they hired some1 else however later on they started publishing the same ad again and again.
