Thank you for submitting your answer. One key feedback I would have is that it is generally expected that you follow the CIRCLES method in answering these kinds of questions (Google search “CIRCLES method product management”).
If I was following the CIRCLES method, I would have first identified various user persona’s that could benefit from the app and then explained my reasoning behind why a particular persona would be of the focus of this app design. I would then list the needs of the particular persona I have in mind. Then I would explain which needs I’d be focusing on and reasoning behind the choices. Finally, I would evaluate the pro’s and con’s of each solution based on three aspects of impact on DMV efficiency (you mentioned it’s the goal), impact on customer experience, and cost of implementation. The final step would be to summarize which features would be prioritized based on the analysis.
I’ll submit a sample answer to this question shortly.
