How to interview on behalf of e-driver?

E-driver answers the questions online first, then takes an interview, a road test, a manual test and an automatic test, including side parking, underground parking, driving in small streets and lanes, driving in downtown areas, and then trains to watch videos and answer questions. Finally, anyone who is qualified can apply. The content of the written test is relatively basic, because the recruitment position * * * uses a volume, and the programming language is not limited. 10 multiple-choice questions and four programming questions. Multiple choice questions include data structure, operating system, etc. Programming problems are mainly algorithms.
