Jimdo Frontend Engineer interview questions

The interview process consisted of multiple rounds of interviews with HR, 2 engineering managers, and multiple developers on the Jimdo team. It took about 6 weeks from start to finish and was an overall pleasant experience

It's kind of weird because I thought I will get an offer. I applied through a job post on StackOverflow. They gave me a project with a deadline of a week. I finished it within 2 days and submitted it. They contacted me after 3 weeks and arranged a meeting a week later. Then they rescheduled it another week later. The video interview was good. I was interviewed by an HR and a Developer. From a technical perspective they only asked me whether I'm comfotable with Typescript or not and that's it. I said yes. They told me that they will talk to the people team and let me know. Then after 2 days the HR told me that my application didn't match their expectation. I mean, are you kidding me or what? How can you know whether I know something or not if you don't ask for a separate technical interview to prove myself first? Very disappointing.
