Intel DSA Interview Questions

What Intel asks in the DSA round

Intel's loop mixes medium DSA with computer architecture, C and low-level memory questions. Bit manipulation and cache-aware reasoning come up often.

Across the 30 questions on this page, the weight sits on these patterns:

• Dynamic Programming — 5 questions · read the dynamic programming guide
• Two Pointers — 5 questions · read the two pointers guide
• Design — 3 questions · read the design data structure guide
• Linked List — 3 questions · read the reversal of linked list (in-place) guide
• Math — 3 questions
• Stack — 2 questions
• Depth-First Search — 1 question · read the depth first search (dfs) guide
• Greedy — 1 question · read the greedy guide

How to prepare for the Intel interview

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