Crowdform Senior Full Stack Developer interview questions

First call of about 30 minutes and then they told me to do a technical assigment, the assigment was about creating a flow with a tool called windmill so I decides to create the app with thech Stack requiered for the position and use this low code tool as much as I can. They told me that I didn't pass the test because of the pack of windmill use... In my opinion It doesn't make to recruit a software Developer to work in NodeJs and React based in how a low code app is used.
