Servicetitan Software Engineer interview typically runs 4 rounds: recruiter screen, coding interviews, and system design. The process usually takes several weeks and is notably long, tool-driven, and speed-focused.

We’ve seen a very consistent pattern at ServiceTitan: the company seems to care less about flashy algorithms and more about whether candidates can implement clean, stack-specific code under pressure. Multiple candidates reported custom dictionary, generic collection, and interface-extension problems in C#, often with follow-on questions about data structure choice, complexity, and even memory behavior. That tells us the bar is practical and opinionated — they want engineers who are comfortable living close to the framework, not just solving puzzles in the abstract.
A recurring theme is that the interviewers often probe speed and completeness at the same time. Several candidates said the work felt manageable in difficulty, but the real filter was finishing quickly enough, especially when the prompt expanded into concurrency, async/await, or recursive downloading/parsing. We also saw repeated requests to explain how async works, how to validate concurrency, and how to test code when the tooling is limited or the environment is awkward. That combination suggests they value engineers who can move fast and defend their implementation choices clearly.
One non-obvious signal: the process can feel rigid, tool-driven, and sometimes under-communicated, so candidates who rely on a lot of back-and-forth may feel squeezed. Our candidates report that the strongest performances came from people who could stay calm, keep the code moving, and make their tradeoffs explicit without waiting for much interviewer guidance. In other words, ServiceTitan appears to reward engineers who are fluent in C#, comfortable with concurrency, and able to prove their code works even when the interview setup is imperfect.

Real interview reports from people who went through the Servicetitan process.
The hardest part for me was actually the system design round, mostly because of how strange it felt rather than because the problem itself was especially difficult. I interviewed for a Software Engineer role at ServiceTitan and the process had four rounds total: one recruiter screen and three technical interviews. The first technical round was a 1.5-hour pair programming session where I had to implement a custom dictionary data structure. That one felt medium or even a bit below medium in difficulty, mostly focused on getting the basics right and writing clean code. The second technical round was another 1.5-hour pair programming session, this time around parallel data processing with async/await. The prompt was to implement an asynchronous web parser using parallel processing, and again it was a solid medium-level coding exercise rather than anything super algorithmic.
The third round was a 1.5-hour system design interview with a Staff Dev and a Manager. At the start, the manager laid out the agenda as 1 hour of design, 20 minutes of behavioral questions, and 10 minutes for my questions. The task was to design a system like TeamCity, so I started by asking clarifying questions about requirements and then moved into the design. About 10 minutes in, the manager just disappeared — camera and microphone off — and never came back. The Staff Dev didn’t address it and kept the interview going, so we ended up spending the whole session on design and never got to the behavioral portion at all. The interviewer said I’d hear back by the next evening, but after two weeks the recruiter told me they had hired someone else. Overall, the technical questions were manageable, but I’d be ready for a fairly long pair-programming format and a system design interview that may not follow the agenda exactly.
Prep tip from this candidate
Practice implementing a custom dictionary from scratch and be comfortable with async/await patterns for parallel processing, since both coding rounds were long pair-programming sessions. For system design, prepare to drive the conversation on a TeamCity-style CI system by clarifying requirements early and structuring the design yourself, even if the interview flow changes.

Synthesized from candidate reports. Individual experiences may vary.
The process typically starts with an internal recruiter or recruiter screen to discuss your background, availability, and fit for the Software Engineer role. In some cases this call is straightforward and brief, while other candidates reported scheduling issues or delays.
Many candidates are asked to complete an online coding challenge early in the process. The problems are often C#- or .NET-heavy and may involve implementing interfaces, custom collections, generics, or a simple ranking/search-style exercise, with hidden tests and limited guidance.
The first live technical interview is usually a long pair-programming session focused on implementing a custom data structure or collection type. Interviewers look for correct code, clean structure, and the ability to explain data structure choices and complexity tradeoffs as you work.
A second live coding round often centers on concurrency or async programming, such as building a multithreaded downloader or an asynchronous parser. Candidates are expected to reason about async/await, parallelism, and testability, sometimes under tight time pressure.
The final stage is typically a system design interview that may also include behavioral or broader technical discussion. Candidates have reported designing systems like TeamCity or a chat system, and the session may include questions about tradeoffs, implementation details, and how you would validate or test the solution.
