Lyft DSA Interview Questions

What Lyft asks in the DSA round

Lyft's loop is graph-heavy — matching, routing and shortest-path shaped problems — alongside a practical coding round and a design discussion on real-time dispatch.

Across the 29 questions on this page, the weight sits on these patterns:

• Breadth-First Search — 4 questions · read the breadth first search (bfs) guide
• Prefix Sum — 3 questions · read the prefix sum guide
• Array — 2 questions
• Backtracking — 2 questions · read the backtracking guide
• Design — 2 questions · read the design data structure guide
• Dynamic Programming — 2 questions · read the dynamic programming guide
• Greedy — 2 questions · read the greedy guide
• Simulation — 2 questions

How to prepare for the Lyft interview

1. 1. Start at the top of the list above. The patterns are ordered by how often Lyft uses them, so the first two or three buy you the most coverage per hour.
2. 2. Solve by pattern, not at random. Doing eight breadth-first search problems in a row is what makes the ninth recognisable in an interview — jumping between topics does not.
3. 3. Tick problems off as you go so the gaps are visible. The per-pattern counts tell you which Lyft topic you have actually covered.
4. 4. Write the approach before the code. Lyft interviews are judged on the reasoning as much as the working solution.
5. 5. Pair this with the pattern guides when a topic is new, and the system design sheet if the role is senior enough to have that round.
6. 6. If this is a campus or off-campus drive rather than a lateral move, the placement preparation guide covers the stages around the DSA round — aptitude, core subjects and the HR interview — in the order they actually happen.
