      Principal Engineer Interview

      14 Jun 2026
      Anonymous interview candidate
      Austin, TX
      No offer
      Positive experience
      Easy interview

      Application

      I interviewed at SpaceX (Austin, TX)

      Interview

      Call with Recruiter for a principal mechanical engineer designing Starlink next gen receiver. Recruiter was nice and honest. She wanted to recommend me for the next round interview but the pay was low compared to what I was making at the time, and the extra long hours were a deterrent for my family. Also, this was Jan 2025 and spacex was already valued around $600bn, so was a little bit late to the party

      Bastrop, TX
      No offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 4 weeks. I interviewed at SpaceX (Bastrop, TX) in Jul 2024

      Interview

      Phone screen from HR followed by Phone screen from manager and a team member. HR interview is non technical. Manager and team interview is technical. If selected, you go onsite. For onsite, they make you do a presentation (on a topic of your choosing). They will even provide a feedback for presentation. And the rest are standard behavioral interview/ just chat. There will a test for technical positions which go back to college equations. A lot of Musk companies have the same culture. Most of the folks are young and eager to prove themselves- so they can seem a little arrogant- but its mostly pride that they accomplished with limited resources and training.

      Principal Engineer Interview

      26 Jun 2016
      Anonymous interview candidate
      Seattle, WA
      No offer
      Neutral experience
      Average interview

      Application

      I applied through a recruiter. The process took 6 weeks. I interviewed at SpaceX (Seattle, WA) in Apr 2016

      Interview

      I was contacted by a recruiter for SpaceX. A few days later, I had a phone interview with the group lead. In the interview, we discussed my experience in general and I was able to ask questions about the group, their work and SpaceX. A few days later, I had another phone interview with a design lead. In the interview, I was asked technical questions and was able to ask more questions about the role, the group and SpaceX. These first two steps went well, so I was presented a design project to complete. I was given approximately one week to complete the design and create a presentation describing my results. I found this to be an interesting way to express myself, but be aware that this can be a double-edged sword - scoping is important. I took a general approach to completing the project since the topic was fairly broad assuming that I could dive deeper during the review. After the week passed, I submitted the project and a review was scheduled a couple of days later. In the review, I was able to present my project, but unfortunately the deep dive didn't occur. The interview lasted 30 minutes with questions along the way and ended rather abruptly at the 30 minute mark. Word to the wise, the project is general by design, but do your best to find out more about specific areas of interest and also find out who you are talking with. Since you will be designing something that would take months of work in reality, these bits of information will help you tailor your work to achieve the best impact. At this point, I received feedback that I wasn't a good match for the role but I may hear back in 9 - 12 months.
