abra Junior Python Developer interview questions

I got a call from hr and then she sent me an home assignment for 4 days building a restAPI. I submitted a full project answering all their requirements. Within one day after submitting they sent me a general rejection letter and didn’t even bother to call me after working on this assignment for full 4 days (during the weekend). I then asked for feedback from them and they said my work was too minimal. Really disrespectful of the candidate time and effort in my opinion.
