Are these based on real engineering roles?
Yes. The catalog is built around real engineering role patterns so the practice round feels closer to a live interview.

SpaceX
Backend
Embedded Software Engineer, Customer Hardware (Starlink)
Write Linux-based embedded software for the custom processors and microcontrollers inside Starlink user terminals and phased-array hardware, owning firmware and low-level drivers that ship to millions of devices in the field. You'd work in C and C++ close to the silicon, balancing performance, memory, and reliability on constrained hardware. A technical interview would probe embedded C/C++ fundamentals, microcontroller and driver-level programming, debugging on resource-constrained targets, and how you reason about firmware that must run unattended across a massive device fleet.
CC++Embedded LinuxSpaceX
Data
Full Stack Software Engineer, Data (Starlink)
Build the data platform and tooling that turns Starlink's telemetry from millions of devices into actionable insight, developing pipelines and full-stack applications that let engineers monitor constellation and network health at scale. You'd work across backend data systems and frontend dashboards, typically in Python, TypeScript, and SQL. A technical interview would probe data-pipeline and schema design for high-volume telemetry, query performance and aggregation at scale, and your ability to build a full-stack tool that ingests and visualizes large, fast-moving operational data.
PythonTypeScriptSQLSpaceX
Backend
Software Engineer (Starlink Ground Network)
Build highly reliable, available software systems for the ground network behind Starlink's satellite internet service, designing fault-tolerant systems that operate for long periods with minimal maintenance while orchestrating the world's largest satellite constellation. You'd own backend services that route and manage traffic across millions of user terminals. A technical interview would probe distributed-systems design, fault tolerance and failure recovery, networking fundamentals, and your ability to reason about availability and consistency in a planet-scale, latency-sensitive system.
GoDistributed SystemsLinuxSpaceX
Backend
Software Engineer, Flight Software (Starship)
Design, develop, and test the software that controls and simulates Starship's flight systems, working across the full stack from application down through operating system, networking, firmware, and simulation in close partnership with hardware engineers. You'd write high-reliability C++ for vehicles where a software defect can lose a mission. A technical interview would probe deep C++ proficiency, real-time and embedded constraints, memory and concurrency management, and your ability to debug low-level software interacting directly with hardware and sensors.

FAQ
Is the interview voice-based?
Yes. ExoForm runs a live voice interview, asks follow-ups, and produces structured feedback after the session.
Can I try it for free?
Yes. You can start with the free interview allowance before upgrading for more practice.
