Arab Administrative Development Organization interview questions

They sent me a message on LinkedIn to share my portfolio and contacts then called me for a interview on call because of the Corona circumstances, then asked me to make a task after that they called me and said you are accepted from the manager and gave me an appointment to signature on the contract. But when I went to there the manager said I didn't receive any from you, I didn't see any tasks and the UX /UI designer job description not only to design but also to work on java script, PHP languages and montage and on the other side no fixed work hours they could work 24/7 without compensation. So that I didn't like to work there.
