Infosys SP DSE Coding Questions and Topics to Practice
Infosys SP and DSE coding questions — the topics, difficulty, and practice list for InfyTQ and Superset coding rounds.
Infosys SP and DSE coding rounds sit above Ninja level. Here is what they actually test and a practice list that matches.
How the SP and DSE coding rounds work
Infosys hires SP and DSE through InfyTQ certification and Superset off-campus drives. Both paths include an online exam with programming questions plus MCQs on Java/Python, DBMS, and sometimes OOP — with SP requiring a substantially higher bar.
DSE questions typically sit at easy-medium; SP questions push into medium with DP and graph problems. Both are timed, so pattern recognition and clean implementation decide the score.
Topics that repeat every year
Arrays and strings (most frequent), hash maps, two pointers, recursion, basic trees, simple DP (Fibonacci-style, knapsack-light, subarray problems), and occasionally graph traversal for SP.
DBMS MCQ topics: joins, normalization, transactions, SQL queries. Language MCQs: Java/Python fundamentals — collections, exception handling, syntax traps.
A practice list by difficulty
Start with easy: reverse a string, frequency counting, array rotation, majority element. Move to medium: subarray sums, longest substring variants, binary search on arrays, tree traversals, and DP with memoization.
For SP specifically, add graph problems (BFS/DFS, connected components) and at least 10 DP problems — DP appears in SP papers far more than in DSE papers.
Where to practice
Use the Infosys SP DSE preparation guide at /blog/infosys-sp-dse-preparation-guide for the full pattern, PYQs from Apply's company library at /pyqs, and Infosys mock interviews at /mock-interview/infosys to rehearse the interview that follows the coding round.
