2 technical rounds, both were 45 minutes long.
Asked basic engineering questions (cantilevered beam, flow through a pipe, hydraulics) that increasingly got difficult.
Must know first-principle engineering to pass the interview.
Cantilevered beam, pressure of a pipe with varying area, hydraulics questions
The following metrics were computed from 46 interview experiences for the SpaceX Engineering Intern role.
SpaceX's interview process for their Engineering Intern roles is fairly selective, failing a large portion of engineers who go through it.
Candidates reported having very good feelings for SpaceX's Engineering Intern interview process.
