Overview

This repository contains example test assignments used during our hiring process at Mat3ra.com.

We find that regular job interview questions can often be misleading and so use the "real-world" examples instead.

Each file represents an assignment similar to what one would get when hired.

Usage

We suggest the following flow:

1. Fork this repository on GitHub
2. Create a branch using your GitHub username as a branch name
3. Create a subfolder with your GitHub username
4. Copy one of the ReWoTe suggestions (.md files) to README.md in that subfolder and modify the content of the ReWoTe as necessary
5. Introduce any changes under the subfolder
6. Submit a pull request into the dev branch of this repository

See dev branch also.

Notes

Examples listed here are only meant as guidelines and do not necessarily reflect on the type of work to be performed at the company. Modifications to the individual assignments with an advance notice are encouraged.

We will screen for the ability to (1) pick up new concepts quickly, (2) implement a working proof-of-concept solution, and (3) outline how the PoC can become more mature. We value attention to details and modularity.

wic's Issues

Improve system interface (game)

Use modern OpenGL techniques

Each object should possess its own vertex buffer object. However, I'd like to make object construction threadsafe, so everything can be done in a separate loading thread. This means that vertex buffer objects must be initialized after object construction, probably with a call to [drawing object].load() (similar to what I did with textures).

make textures more thread-safe

Unfilled shapes

Networked stage

Ditch colors and adopt shaders

I'll start with 3 shader programs:

1. Colored object
2. Bordered object
3. Textured object?

Sound

Update freetype and glfw

Might fix input issue

Actor/Map framework

Lighting

Collision detection

Better exceptions

Document thread safety.

Provide basic UI elements

UI elements to include:

1. Buttons
2. Input boxes
3. Sliders
4. Drop-down menus
