Snowflake DSA Interview Questions

What Snowflake asks in the DSA round

Snowflake runs a demanding loop: medium-hard DSA, SQL depth, and a design round on storage, query planning and multi-tenant isolation.

Across the 104 questions on this page, the weight sits on these patterns:

• Breadth-First Search — 17 questions · read the breadth first search (bfs) guide
• Dynamic Programming — 16 questions · read the dynamic programming guide
• Depth-First Search — 9 questions · read the depth first search (dfs) guide
• Design — 9 questions · read the design data structure guide
• Binary Search — 7 questions · read the modified binary search guide
• Greedy — 7 questions · read the greedy guide
• Two Pointers — 5 questions · read the two pointers guide
• Stack — 4 questions

How to prepare for the Snowflake interview

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