Interview process

1. Phone screen.
2. Virtual technical interview with one engineer. The candidate described the question in that round as easy.
3. An all-day onsite that ran for roughly six hours without breaks.
4. A series of engineers took turns asking technical questions in one-hour blocks.
5. The final interview was behavioral and was conducted by the project manager.

The candidate found the onsite environment and energy at Starbase memorable, but reported that maintaining peak performance for six straight hours without a break became difficult. The candidate believed the process tested how long someone could continue performing under pressure and cautioned that strong motivation for the company's mission mattered because of the intensity.

Reported system-design question

Design a Starlink purchasing and fulfillment service that can absorb severe spikes in demand, such as a sudden wave of purchases after a high-profile post by Elon Musk.

The report lists this as one standalone question. It gives the virtual technical interview the only singular question cue, while the onsite is described as a larger series of technical questions. The available evidence therefore supports the virtual technical round as the most likely placement, but the source does not state that connection explicitly.

The corresponding FastPrep exercise is Design High-Demand Commerce and Fulfillment. Its detailed ordering, inventory, admission-control, warehouse, and shipment requirements form a reviewed practice contract rather than additional claims about the interview.
