I applied online. The process took 3 weeks. I interviewed at Lucid Motors (San Francisco, CA) in May 2022
Interview
It starts with behavioral Interview with directors. The major part of the interview process is to complete a take home assignment for optimization (manufacturing optimization) including both formulation and coding. There is one follow up on take home assignment and some discussion on MILP/LP open source solvers and their performances. After that, there are more meetings with other directors. Given that this is a small startup, the interview process is fairly personal and thorough.

Question 1
My Experience level and what interested me about the Company
I applied online. I interviewed at Lucid Motors in Jun 2023
Interview
Applied online, no referral. Signed an NDA so no specific details provided below but rather a high-level overview. 1st round was a typical HR screen "tell me about yourself, what you're looking for etc". Asked if I'd be comfortable with RTO 5 days/week at their Newark office.
2nd round was a tech screen with a few different parts:
1) LC style coding - first question was a basic hashmap question, next question was a tricky variant of two-sum.
2) ML theory - refresh your fundamentals on loss functions, metrics, statistical tests / concepts (ex. independence)
3) Resume deep-dive.
I moved on to the on-site, but I was never told what to expect for each round even though I asked 3 times over a couple of weeks. Very, very unprofessional. but sadly a common experience these days in the interview process. I withdrew from the process as I already received an offer.

hashmap question, two sum variant, ML theory questions
I applied online. The process took 4 weeks. I interviewed at Lucid Motors in Jan 2023
Interview
Very well defined interviews, assessing your skills across, coding, design, ML deep dive and behavioral. Make sure to prepare for ML design questions well. Not a typical design problem. But rather ones you can expect from automotive field e.g. based on telemetry data etc.
