Specialist Programmer reports describe a problem-solving bar that can differ from other Infosys fresher roles. This page draws on three candidate accounts, including a 2024 campus experience. One writer explicitly says they cannot remember the exact OA questions; those prompts are not reconstructed here.
Specialist Programmer: assessment and interview prompts
In a 2024 campus report, the OA had three problems. The writer remembered a segment-tree problem, an ad-hoc problem whose statement they could not recall, and a recursion problem involving combinations. Only the first and third can be described, and neither is turned into a new problem statement. The interview then included a short tree traversal, LFU Cache, and a design discussion about filtering an e-commerce order list by COD or prepaid payment. These details are in the Infosys Specialist Programmer offer report (2024).
A separate selected candidate described a technical interview with the Celebrity Problem, asking for an efficient stack-based approach (source), followed by a shortest-path question based on Dijkstra that was changed into a dynamic-programming discussion (source). The Infosys SP interview report does not state a date in its accessible text.
Another 2024 interview included Remove Invalid Parentheses (source), a SQL query for employees with the second-highest salary (source), and fundamentals questions about deadlocks, transactions, joins, OOP pillars, and the difference between a thread and a process (same report). These appear in the Infosys Specialist Programmer accepted report (2024).
How to prepare for an Infosys Specialist Programmer interview
These reports point to a useful split: practice advanced DSA, but do not neglect the interviewer's ability to move from code into database or system design. For LFU Cache, be prepared to explain the data structures and update rules. For SQL, work through ties in salary values and make your assumptions explicit. The system design question guide and interview question bank offer broader preparation.
The experiences are not an official Infosys process and are not interchangeable with the Ninja or Digital profiles. Check the profile named in the invitation before using this list.
