First round with the hiring manager: past experience + technical questions.
On site: 3 rounds (two coding + one behavioral with the hiring manager)
Final round with the director of the team
Interview questions [1]
Question 1
Describe your previous project relevant to the position.
I applied online. The process took 2 weeks. I interviewed at Cyngn (Mountain View, CA) in Oct 2025
Interview
First had video call with HR rep, then video call with hiring manager. Then was invited on-site the following day. to meet hiring manager. Also met with Engineering Manager. Then later that afternoon had a video interview with Engineering VP. The HM was asking what day I could start and the time I should arrive. This all sounded positive. I then emailed the HR rep a few days later for a update and never got a response. I have heard nothing since those interviews. GHOSTED.
No chat, straight to an assessment requesting I create Canva slides based off very general guidelines. Free work despite sharing my extensive portfolio...what else is new? But I played the game and got a generic rejection soon after submission. I don't recall saying anything about being a mindreader in my resume.

Interview
I recently interviewed for the Senior C++ Robotics Engineer role. Despite preparing extensively and having years of experience in autonomy, path planning, and ROS-based development, the interviewer focused solely on control theory questions and ended the interview abruptly when I didn’t respond immediately.
The question itself was extremely basic (involving trigonometry), and while I interpreted it more broadly at first, the lack of communication or interest in my thought process was disheartening. The interviewer did not say goodbye, provide feedback, or even acknowledge my background. It felt dismissive and discourteous.
For a company seeking engineers for planning and behavior modules—not a pure control role—it’s surprising that the interview focused exclusively on control-related questions without context.
I believe interview processes should aim to assess holistic skills, critical thinking, and relevance to the job—not just gatekeeping with a single math question. I hope Cyngn reconsiders how it evaluates candidates, especially experienced ones.

Question 1
If a bicycle model is moving at velocity V and heading angle θ, what is its velocity in the X and Y directions?
This was the only technical question asked. While the math behind it is simple (V * cos(θ), V * sin(θ)), the interviewer showed no interest in hearing my thought process or discussing my actual experience with vehicle models, ROS, or planning systems. No questions were asked about my resume or relevant project experience.
