Salesforce DSA Interview Questions

What Salesforce asks in the DSA round

Salesforce blends medium DSA with deep OOP design and platform-specific knowledge. Expect strong questions on data modelling.

Across the 220 questions on this page, the weight sits on these patterns:

• Dynamic Programming — 48 questions · read the dynamic programming guide
• Binary Search — 18 questions · read the modified binary search guide
• Greedy — 18 questions · read the greedy guide
• Breadth-First Search — 13 questions · read the breadth first search (bfs) guide
• Depth-First Search — 12 questions · read the depth first search (dfs) guide
• Sliding Window — 9 questions · read the sliding window guide
• Two Pointers — 9 questions · read the two pointers guide
• Design — 8 questions · read the design data structure guide

How to prepare for the Salesforce interview

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