Uber Frontend Interview Experience

I recently came across an interesting frontend interview question asked at Uber, and I tried solving it. Sharing the problem and my solution in case it helps someone preparing for frontend interviews.

Frontend Interview — Shape Interaction

Uber provided a 2D array and asked to create a shape.

The shape consists of empty boxes, and each box can be turned into a filled box upon interaction.

The requirement was:

• Click/interact with the boxes to fill them.

• Once all boxes are filled, the boxes should be deselected in the order of selection.

I tried solving this question and recorded my approach and solution here:
