I applied online. I interviewed at Zipline (South San Francisco, CA) in Apr 2024
Interview
First technical screen - 45 minutes - talked about stuff from my resume, followed by basic questions about applied aerodynamics, flight dynamics, stuff like if you are in an airplane and you activate aileron, what happens to the altitude, speed etc.
Take home design assignment - 6-7 days of time
1 hour interview - Design problem - design a system to clear water off the camera, while flying
Project presentation to a panel.
Final round - Highly technical flight dynamics questions eg. which parameter decides how quickly a fixed wing plane can gain altitude etc.

Question 1
1. what happens to the altitude, speed etc.
2. design a system to clear water off the camera, while flying
3. which parameter decides how quickly a fixed wing plane can gain altitude
Very easy straight forward. The interview was very formal they asked about my experience in current roles and my outcome for searching in the job market. They were very enthusiastic about having me go to the nearest location for the final part of the interview.

Interview
Extractive and shady hiring process. Multiple rounds followed by on-site and asked heavily specific questions.
A large share of the questions were strikingly specific to live challenges the team is currently working through, not hypotheticals or standard competency questions, but "here's a real thing we're stuck on, how would you approach it." Each time I gave a substantive answer, interviewers pushed for more: specific suppliers, real numbers, methodology, the actual playbook. At some point it stopped feeling like an evaluation of how I think and started feeling like a working session where I was the only person in the room not getting paid for it.
If you're coming from an adjacent industry, understand that your perspective on their open problems may be the thing they're actually after. My advice to anyone entering this loop: talk about how you'd approach problems at a framework level, and be cautious about handing over the detailed, company-specific solutions you've built elsewhere until there's a real offer on the table.

Question 1
What would you do if there is a design change coming but supplier has 4 weeks lead time to change tooling?
