Juspay DSA Interview Questions

What Juspay asks in the DSA round

Juspay's process is unusually hands-on — long machine coding and debugging rounds — alongside medium DSA and payments-flow design questions.

Across the 21 questions on this page, the weight sits on these patterns:

• Greedy — 4 questions · read the greedy guide
• Dynamic Programming — 3 questions · read the dynamic programming guide
• Breadth-First Search — 2 questions · read the breadth first search (bfs) guide
• Graph — 2 questions · read the graphs guide
• Simulation — 2 questions
• Sliding Window — 2 questions · read the sliding window guide
• Binary Search — 1 question · read the modified binary search guide
• Depth-First Search — 1 question · read the depth first search (dfs) guide

How to prepare for the Juspay interview

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