Atlas Systems Software Developer interview questions

I applied through the job board. They called me to ask my background then she asked me when you will be available for an interview. I said Tomorrow at Any time i will be available. Just schedule and inform me. She got angry and started to argue that we have to wait for you. Make no sense. Next day afternoon i have an interview. I was present there Before 1 hour of my interview time. They started the process after 3 Hours. They sent a link to the exam. i wrote an exam in front of them, In their laptop. The laptop has a popup so i got warnings. I informed the Who proctoring me. But it's not solved. The platform was absolutely worthless. SQL Like operation not working in that application. Then i went back home. i got Rejection mail. The questions are simple but the platform is bad. Some of them said they do not follow the code of Rules.
