Loop Commerce Front End Developer interview questions

Interview was easy, typical phone questions with basic questions and then technical challenge to create a small Image Gallery in 50mins. Can use jquery only. No other library. Interviewed Friday last hour and got an email Monday morning saying that I am not a fit after "review with team". What would have been good is to get actual feedback and just a flat no. I had a working solution within allotted time albeit not perfect but nice to get real feedback. Interviewer didnt seem very excited from beginning and seemed rushed and withdrawn from the call.
