So it all started with a call from a recruiter to arrange a technical interview. I've made a lot of interviews in companies outside and inside of Egypt this year. I can say frankly this is the worst technical interview experience. Most of their questions are at a very senior/lead-level software engineer role. Very little has to relate to mobile development. See the examples of the questions below. Above that, they wanted me to open the camera while they didn't. Very little feedback and they didn't seem to want to help. My tip: Think about your interview questions again to not waste your and my time.
