ADP Software Engineer interviews reported here reward comfort across several practical areas rather than a single narrowly focused algorithm session. One candidate described three rounds covering DSA, notification-system design, and team working style. Their coding prompts focused on string and linked-list data structures and algorithms, while the design prompt was to create a notification system.
A separate Software Engineer account describes an HR call followed by an online assessment and one or two technical-panel interviews, with a broad Java-heavy discussion. Topics included straightforward coding, SQL joins and sorting, Java concurrency and OOP, JavaScript promises, backend concepts, and behavioral questions about conflict and deadlines. That candidate characterized the coding questions as relatively easy, but the rapid movement between fundamentals and stack-specific concepts as the challenge.
Prepare by practicing concise explanations as well as implementation: work through string and linked-list problems, be ready to structure a notification-system design, and revisit the Java, SQL, and JavaScript concepts named above if they match your background. Have concrete examples of how you work on a team, handle conflict, and meet deadlines. The available reports are limited, so team-specific sequencing and technical depth may differ.

The part that stood out most was how much the interview leaned on the basics and on whatever I had put on my resume. The first round started with a self-introduction, then they moved into questions based on my background, the programming language I listed, and the projects I had worked on. A lot of the discussion was scenario-based, so it wasn’t just “can you code,” but also “how did you handle this situation” and “what was your role on that project.” I also got a few basic Python questions and short programming exercises, which felt more like checking fundamentals than pushing into anything very advanced.
The process itself was pretty straightforward. I had an initial phone screen with HR that lasted about 30 minutes, then a technical coding round that was done on paper and took around 1.5 hours, and after that a technical discussion with the team lead for about an hour. In the technical rounds, they asked things like the software testing life cycle, different types of testing, how I write test cases, the difference between manual and automated testing, and how defects are handled in a testing process. There were also SQL and database questions, especially joins and how to write complex queries for database testing. In the Java-focused discussion, they asked about the difference between an abstract class and an interface. One question I remember clearly was explaining how I optimized a sorting algorithm in a previous project, because they wanted to hear my thought process, not just the final answer.
Overall, the interview felt fair but broad, covering coding, fundamentals, resume depth, and communication. I ended up getting an offer after about a week. My main takeaway is to be ready to talk through your own projects in detail and to review the basics of your main language, SQL joins, testing concepts, and how you explain tradeoffs in past work.
Prep tip from this candidate
Be ready to explain your projects and resume line by line, including your role and any optimization decisions you made. Also review testing fundamentals, SQL joins, and the difference between an abstract class and an interface, since those came up directly.

Synthesized from candidate reports. Individual experiences may vary.
One Software Engineer candidate reported beginning with an HR call followed by an online assessment. The report does not specify the assessment format, so candidates should expect an initial screening sequence but avoid assuming identical content across teams.
Candidates report coding questions on string and linked-list data structures and algorithms. Another account describes relatively easy coding alongside Java concurrency and OOP, SQL joins and sorting, JavaScript promises, and backend concepts; the breadth may matter as much as algorithm difficulty.
A three-round candidate report included designing a notification system. Practice explaining components, data flow, and tradeoffs clearly; the report identifies the prompt but does not establish a universal design-round format.
Candidates report questions about prior experiences, team working style, conflict, and handling deadlines. Prepare specific examples that show how you collaborate and make decisions, since these discussions may appear alongside technical questions.
