ShopBack Senior Android Developer interview questions

Android Coding: the interviewer gave me a zipped prject (even no github clone!!!) and it did not compile on my end, his intention is to make a recyclerview for the data source they provided at the code, then as the project was not compiling I had to show him my open source code which has a similar functionalitiy Coding -> I provided two different working solution for the same problem System design : he gave me a problem about I believe current problem maybe they already solve, and I could provide like 3 solutions then in the system design he asked me about (Json Structure) which I provided an answer according to my previous experience even told him about the json error. After all I got rejected with no detailed feedback. the experience for me is very bad as the interviewer does not have any collaboration or communications with me He just wanna I believe specific answer or so. I did not gain any new knowledge from that interview that is why I am really not happy.
