Interviewed for a software engineer role at Warp and got a design question that felt very on-brand for a terminal app company. The problem was more involved than it looked at first glance.
  • Design a data structure that models a terminal application with multiple tabs and split panels. Each tab should contain a panel layout modeled as a tree, where splits create child nodes. Implement methods to create tabs, split panels, serialize the full state, and deserialize it back. Write a test that creates tabs, does nested splits, serializes, deserializes, and verifies the result matches the original.

“The tree structure for panels clicked pretty fast since split panes are basically recursive by nature.”

Coding round for a software engineer role at Warp, focused on a tree data structure problem involving terminal pane splitting. Pretty niche problem, felt like it was testing both OOP design sense and string rendering logic at the same time.
  • Design and implement a PaneTree class that supports splitting terminal panes either vertically or horizontally. Each split should replace a leaf node with an internal node containing the original view and a new view as children. Implement a split(viewId, direction) method and a toString() method that produces a deterministic textual layout of the current pane structure.

“This one took me longer than it should have to get started.”
