Applicable Experience & Durations
The goal of this challenge is to build the backend of the interactive presentation system.
Some of the tasks include:
- Designing a scalable database schema that allows to handle occasional spikes in requests to the system (e.g., imagine 30k people all voting at the same time);
- Making sure that no data can be lost due to a race condition when voting or fast-forwarding slides;
- Writing unit tests for the provided code;
- Organizing code in a readable and maintainable way.
The candidate gets access to a private GitHub repository with the task description, a project boilerplate, and API tests.
They submit their solution by creating a Pull Request.
The evaluation is based on the results of the automated functional tests and the code review scorecard that covers more advanced aspects within the target competence.
