Quora DSA Interview Questions

What Quora asks in the DSA round

Quora asks medium-hard problems on graphs, heaps and ranking-shaped questions, with a design round on feed generation and content quality at scale.

Across the 19 questions on this page, the weight sits on these patterns:

• Design — 3 questions · read the design data structure guide
• Array — 2 questions
• Math — 2 questions
• Prefix Sum — 2 questions · read the prefix sum guide
• Sliding Window — 2 questions · read the sliding window guide
• Bit Manipulation — 1 question · read the bitwise xor guide
• Breadth-First Search — 1 question · read the breadth first search (bfs) guide
• Hash Table — 1 question

How to prepare for the Quora interview

1. 1. Start at the top of the list above. The patterns are ordered by how often Quora 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 design 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 Quora topic you have actually covered.
4. 4. Write the approach before the code. Quora 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.
