Practice with the full bank, then narrow into a path.
Your active path is foundations track, but the catalog stays broad by default so you can spot harder reps, switch contexts quickly, and still return to the path that best matches your current goal. Starter includes 160 free problems and marks 94 Pro-only problems before you open a gate.
Start broad, then focus when you want structure.
Company labels help frame practice in a familiar business context. They are directional study aids, not official interview guidance from the companies listed. We keep all paths visible first so hard questions do not disappear.
