Candidates describe a ServiceTitan Software Engineer loop built around a recruiter screen, long pair-programming rounds on custom collections and async code, and a system design interview, often in C#.

Across the Software Engineer reports, the coding rounds stand out. Several candidates describe implementing a custom dictionary, in one case by completing a C# interface, and another mentions a generic ICollection. Custom collection and interface implementation is the most repeated theme, so practice building these from scratch in a plain editor, ideally without IntelliSense. One candidate also notes that the interviewer watched how they chose data structures, reasoned about complexity, and avoided memory leaks in .NET.
A second theme is concurrency. Candidates describe an asynchronous web parser, parallel data processing with async/await, and a multithreaded downloader that follows links recursively. One was also asked to explain how async/await works and why they chose a particular built-in structure, so be ready to talk through your choices as you code.
Speed appears to matter. One candidate felt a 90-minute window carried an unstated expectation of finishing in about 60 minutes, even with passing unit tests. Aim for working code first, then explain tradeoffs.
System design appears in at least some loops. One candidate was asked to design a TeamCity-style CI system, and another described a final round covering system design plus a broader technical discussion. Some HackerRank tasks had incomplete instructions, so read the provided tests carefully. Candidates also report slow or missing recruiter communication, and all reported outcomes were no offer, so confirm next steps with your recruiter.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report starting with a recruiter or HR screen. One describes it as a one-hour screening, and another found it straightforward. One candidate reports a scheduled call that never happened, so confirm timing in writing.
Candidates report a first technical round, often about 1.5 hours, in a browser editor such as HackerRank. Reported tasks include a custom dictionary, a C# interface implementation, and a generic collection. One candidate described the difficulty as medium or below, and another reports a tight, speed-focused format.
Candidates describe a second coding session on asynchronous or parallel work, such as an async web parser or a multithreaded downloader that recursively follows links. Interviewers may ask you to explain async/await and your data-structure choices. Time pressure is a recurring complaint, so practise finishing working code efficiently.
A final round in some loops covers system design. One candidate was asked to design a TeamCity-style CI system, and another describes system design plus a broader technical discussion. One agenda included behavioral time, but that candidate's session ran entirely on design. Clarify requirements early and drive the structure yourself.
