Neutral ExperienceNo Offer

Process

The process was a first-round HR interview, two rounds with a hiring manager and a senior engineer, and a last round that will be an on-site presentation. It was a very standard FAANG process, asking you to solve a problem on the spot. You should be ready for anything, because a small mistake can screw you over.

Questions

I can say due to NDA, but honestly, it was not too different from other technical questions from Elon’s company. There is no need to be so secretive about it. You didn’t invent these questions.

Never dull

Mechanical Engineer • Current Employee

November 1, 2023

Pros: There is a lot of work with a lot of variety. At this company, if you don't define your scope of work, others will by continually asking you to take on more responsibility. Which is great, if you're ambitious, capable, and love to take on responsibility! Overall, the work is great.

Cons: Time off policy is too good! This is great on a personal level, if you need or want to take time off. However, on a project level, this definitely impacts who will be available and when. More time off per person means we need more persons, so maybe that's actually a good thing for job seekers...
