It was a pretty easy question, but the interviewer was very unprofessional and didn't tell me all of my options. It turns out I could have done it with AngularJS, and when I asked if it was possible, the interviewer told me that it was not. So, I did it with React, which I am not familiar with, and didn't pass the test.

After I finished the test, another interviewer came and asked if I had any problems. So I told him that I had done it with a framework which I am not familiar with. He then told me that he didn't know why, but I should have had the option to do it with all frameworks.

So, it looks like a good company from the outside, but the overall experience was very unprofessional.

Build a "ToDo" list exactly as the design you received.
