Our candidates report that ServiceNow is not treating the AI Engineer loop like a pure model-building interview. The clearest signal is the assessment itself: it mixes hard coding, SQL, MCQs, and prompt-writing, which tells us they want people who can move comfortably between algorithmic problem-solving and practical systems thinking. One candidate described the coding questions as genuinely difficult rather than pattern-recognition exercises, and the SQL prompt as something that required careful reasoning under pressure, not a quick join-and-aggregate answer.
A recurring theme is that ServiceNow seems to care about breadth with depth. The prompt-engineering task is especially revealing for an AI role: they are checking whether candidates understand how to shape model behavior, not just how to call an API. We’ve also seen that the core CS and DSA pieces are used as a filter for fundamentals, so candidates who over-index on AI buzzwords without solid technical grounding tend to struggle. The non-obvious trap here is assuming the SQL or prompt section will be secondary; in this process, every part appears to carry real weight, and the strongest candidates are the ones who can stay precise while switching contexts quickly.

Real interview reports from people who went through the Servicenow process.
The process was pretty straightforward on paper, but the actual screening round was tougher than I expected. The first round was a HackerRank OA, and it packed in a lot: two coding questions, one medium and one hard, plus a very difficult SQL query, two MCQs, and a prompt-writing task. The coding portion felt like the main filter, since the questions were described as hard and required real problem-solving rather than just memorized patterns. The SQL question was also not a simple join or aggregation; it was the kind of query that would take time to reason through carefully under pressure.
What stood out to me was that the assessment wasn’t just about coding. They were clearly checking a mix of DSA, SQL, and prompt engineering, so you had to switch gears quickly between different kinds of thinking. The second stage, if you clear the OA, is an on-campus 2-hour assessment that includes a prompt engineering question, one DSA problem, one core CS MCQ section, and one SQL query. I didn’t get past the process, so I can’t speak to anything beyond that, but the overall vibe was that they wanted strong fundamentals across the board. My takeaway is to prepare for a fairly dense OA and not assume the SQL or prompt part will be lightweight just because it’s an AI Engineer role.
Prep tip from this candidate
Practice solving at least one hard HackerRank-style coding problem under time pressure, and make sure you can handle a very difficult SQL query plus a prompt-writing task in the same sitting. The OA clearly tests breadth, so don’t focus only on DSA.

The process starts with a dense HackerRank screening that serves as the main filter. It includes two coding questions, usually one medium and one hard, plus a very difficult SQL query, two multiple-choice questions, and a prompt-writing task. Candidates are tested across DSA, SQL, and prompt engineering, so the assessment requires switching between different kinds of problem-solving under time pressure.
Candidates who clear the online assessment move to a 2-hour on-campus assessment. This stage includes one prompt engineering question, one DSA problem, a core CS multiple-choice section, and one SQL query. The round continues the broad-fundamentals focus and appears designed to verify both technical depth and comfort across multiple formats.
Across both stages, the interview process emphasizes strong fundamentals rather than a narrow AI-only skill set. The coding questions were described as hard and required real problem-solving, while the SQL portion was intentionally non-trivial and time-consuming. This suggests the company is looking for candidates who can reason carefully across algorithms, databases, and prompt design.
The available experience did not include later interviews beyond the assessment stages, but the outcome was decided after the screening process. Based on the report, candidates either advance after the on-campus assessment or receive a rejection without additional rounds.
