ServiceNow SDE hiring process typically includes: Online Assessment (DSA, coding, aptitude), 1–2 Technical Interviews (data structures, algorithms, OS, DBMS, OOPs, projects), System Design Round (scalable architecture, real-world design), and HR Round (behavioral questions, teamwork, culture fit, salary discussion).

I was asked two questions in the coding round: one on bit manipulation and another on graphs. The second section focused on SQL, and it included a very advanced problem. Finally, there was a prompt-engineering task, which was the only one where I achieved full test-case passes.
