Gusto·Software Engineer·Onsite - System Design / Architecture
May 2026
Gusto system design round focused entirely on a shift scheduling platform for a restaurant chain. Pretty deep dive covering data modeling, service architecture, and scalability concerns. Felt like a reasonable scope for the time given, though the Friday publish spike discussion caught me a bit flat-footed.
- Design a shift scheduling system for a company that operates many restaurants, where managers publish weekly schedules every Friday for their employees to view.
- How would you structure the backend services for this system, covering schedule creation, publishing, employee access, and notifications?
- How do you handle the scalability challenges here, particularly the read-heavy access pattern employees create throughout the week and the spike in write traffic every Friday when managers publish schedules?
“I started with the data model because that felt like the safest ground.” The rest of the author's notes on Software Engineer interview at Gusto, Onsite - System Design / Architecture round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
