CRED DSA Interview Questions

What CRED asks in the DSA round

CRED weights engineering craft and design taste heavily. Expect hard DSA plus a strong machine coding round judged on code quality, not just correctness.

Across the 60 questions on this page, the weight sits on these patterns:

• Dynamic Programming — 13 questions · read the dynamic programming guide
• Design — 4 questions · read the design data structure guide
• Greedy — 4 questions · read the greedy guide
• Sliding Window — 4 questions · read the sliding window guide
• Backtracking — 3 questions · read the backtracking guide
• Divide and Conquer — 3 questions
• Two Pointers — 3 questions · read the two pointers guide
• Union Find — 3 questions · read the graphs guide

How to prepare for the CRED interview

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