They have really quick communication and fast interview process, usually will get back within 2-3 days. You will have opportunity to select days and times of interviews. Pretty open to rescheduling as well.
I applied through an employee referral. I interviewed at Luma AI in Feb 2026
Interview
8 LeetCode questions to complete in an hour on the CodeSignal platform. The questions were very long and felt a bit AI-generated. What you need to implement is not difficult at all. It is reading these long questions.
Questions are numpy/tensor manipulations
Multiple steps, that happened in sequence:
- Hiring manager screen
- 3 technicals, all schedule after passing the last
- Discussion with a recruiter
- Discussion with CEO
This was 6 total interviews where you had to pass one to be scheduled for the next.

Question 1
Combination of technical and behavioral. All pretty typical interview fair.
