I met ServiceTitan at my college career fair.
Stage 1. Quick phone call with a technical recruiter.
Stage 2. Online coding assessment.
Stage 3. Skype call with an engineer that primarily involved coding on a shared screen.
Stage 4. Onsite interviews at HQ. Three back to back technical interviews, including one with the CTO.
The recruiter stayed in constant contact with me and always provided feedback within a day of my interview. Everyone I met at ServiceTitan was extremely welcoming. Overall, the interview process was very smooth and well organized.
