I applied online. I interviewed at Mariana Minerals (San Francisco, CA) in Dec 2025
Interview
Fairly lengthy, 3 individual interviews followed by case study presentation and half day talking to different team managers for fit. Pay attention to presentation time limit, assume less is more to make time for questions. Most things get slowed down a bit getting multiple team members on the call.
Interview questions [1]
Question 1
Do you have any experience in designing industrial scale process units?
