What test tasks for the Junior position would you suggest?

Question

JavaScript

Good afternoon. In connection with the job search for the position of a junior developer, they gave a test task. I found it interesting.
It looked something like this, for those who are interested:
Tools: Rails, PostgreSQL. And anything else you deem necessary.
1. Generate a database of random buildings in Moscow. Number of records: 50. Fields: address, coordinates. Buildings must be real.
The building generation method is best put in the seed.
2. Create a single page application. At the top of the page is a map.
When you click on the map, immediately below it, a table is displayed with:

2.1) all the buildings from our database within a 4km radius (from the click),
2.2) the distance from the click to each of these buildings.

The table should be sorted by this distance.

What would you recommend job examples for a junior developer position?

Answer 1

Write a simple chat with jQuery and Rails on websockets. The principle of the chat is based on rooms, everyone in the same room can see each other's messages. The room has an admin, by default the admin is the creator of the room, the admin can kick and ban users, as well as change the admin, if the admin left the room, then it is deleted. The history is saved on the server and cached on the client by timer and size, if the room is deleted, then the cache and history are reset. You can force download the history by clicking the button. Ajax history loading.
