Focus on what matters

Existing solutions for remote system design interviews are painful to use because they are not designed for interviews. Time is wasted before, during, and after each interview, not to mention the poor interview experience overall. Oasys solves all these problems so you can focus on what matters.

Focus Modes

Distraction-free diagram mode and whiteboard brainstorming mode let candidates focus on designing while keeping the context around.


Doing elementary math and text formatting on a virtual whiteboard is not the focus of an interview, so we provided these out of the box.

Twice as effective

Design Twitter timeline and search question with Oasys uses less than half the time compared to other leading whiteboards.
