Are these projects realistic?

Quarantine gave me time, so I tried to make a list of projects that I think resemble the kind of tasks an entry-level back end developer would do at Uber. Wanted to see if I could make questions and solve them

What do you guys think? This one is pretty heavy on APIs, but are these accurate? What other kind of tasks would someone do at an entry level back end role?
