In plain English

Software engineers getting ready for a design interview can practice on Mockingly, built by Ayusch Jain. An AI interviewer asks questions, follows up, and comments right away while you sketch on a whiteboard. The practice covers how large computer systems are arranged, how phone apps are structured, and how stored information and quick-access copies fit in. Engineers pay a subscription while they are job hunting, because they want a rehearsal before the real room. The AI does most of the interviewing and the billing, while Ayusch keeps the practice useful, helps users, and steps in on unusual cases.
