      Supplier Development Engineer Interview

      9 Jan 2026
      Anonymous employee
      Redmond, WA
      Accepted offer
      Difficult interview

      Application

      I applied online. I interviewed at SpaceX in Feb 2026

      Interview

      I only had an initial screening interview for this position before deciding to pursue a different role at SpaceX, since candidates can only interview for one position at a time. The screening lasted about 30 minutes and consisted mostly of behavioral questions, along with a few technical questions.

      Interview questions [3]

      Question 1

      What are the four types of manufacturing?
      Answer question

      Question 2

      How do you define excellence?
      Answer question

      Question 3

      Give an example of a route-cause scenario, and if you can, tie it to PCB manufacturing.
      Answer question

      Difficult interview

      Application

      I applied online. I interviewed at SpaceX (Redmond, WA) in Nov 2025

      Interview

      The interview process, for me, consisted of four parts: 1.) Initial phone screen with the hiring manager. The interview was a mixture of technical questions and motivation. 2.) Technical phone screen; deep-dived into a technical project. This was solely technical and I was not asked any behavioral questions. 3.) On-site panel interview followed by 1:1s with people on the panel. The panel presentation was 50 minutes and focused on a technical topic that I presented on, then I had 1:1s with the people on the panel. Questions were largely technical and based on the topic I presented on, or adjacent topics that came up during conversation. 4.) "Executive Phone Screen" with a Director. Asked a lot of seemingly random questions that seemed aimed at probing my personal motivation. No real technical questions asked.

      Interview questions [3]

      Question 1

      Why do you want to work for SpaceX?
      Answer question

      Question 2

      What is the difference between Cpk and Ppk? When should you use one or the other?
      Answer question

      Question 3

      What are the pros/cons of a single-sourced part vs. a dual-sourced part.
