Nielsen’s Software Engineer interview reports point to a coding-first process with role-specific variation. Two candidates described an online assessment before interviews: one had two coding questions plus 24 DBMS, OOP, and OS multiple-choice questions, while another report described DSA questions and MCQs. Prepare to solve easy-to-medium problems clearly, since reported examples included two pointers, hashmaps, strings, greedy techniques, dynamic programming, graphs, and a Four Sum-style problem.
The live technical stages also tested how candidates explain their work. One candidate completed two DSA rounds followed by a managerial round with project discussion and questions on database internals, OS, DBMS, and computer networks. A separate account described a screening, low-level design exercise, and system-design discussion: the design prompts involved a parking lot and a scalable URL shortener, with follow-ups on APIs, schemas, caching, load balancing, sharding, reliability, edge cases, and trade-offs. Treat those design prompts as one candidate’s experience, rather than a fixed template.
For preparation, practice reaching a well-reasoned solution—not merely a working one—then narrate complexity, assumptions, and alternatives. Refresh SQL and core CS concepts, and prepare a concise walkthrough of projects, tech choices, and outcomes. The available Software Engineer reports do not state a shared end-to-end timeline.

Real interview reports from people who went through the Nielsen process.
Had 3 rounds: Screening, LLD and System Design. Screening covered DSA with Four Sum, Meeting Rooms II and graph problems. LLD involved designing a Parking Lot using SOLID and design patterns. System Design focused on a scalable URL Shortener, discussing APIs, DB schema, caching, load balancing, sharding, reliability and trade-offs. Interviewers also asked follow-up questions around edge cases, scalability and why I chose particular approaches.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report that an assessment may come first. One Software Engineer account had two coding questions and 24 MCQs covering DBMS, OOP, and OS; another described DSA questions plus MCQs. Expect the exact format and difficulty to vary by hiring path.
Candidates report two DSA-focused rounds in one path and a screening round in another. Reported problems included two pointers, hashmaps, strings, greedy methods, dynamic programming, graphs, and Four Sum. Be ready to justify the chosen approach and discuss edge cases.
One candidate reported a managerial round covering projects, database internals, OS, DBMS, and computer networks. Another reported low-level design of a parking lot and system design of a URL shortener, so design depth may depend on the interview path.
