I applied online. I interviewed at Phoenix Tailings (Burlington, MA) in Jan 2026
Interview
came in and company has around 90 people and saying they will build a lot of factory in the world, however doesn't seem true to me. Willingness for sponsor and saying if you need one they are happy to provide. A lot of work load seems like.

Interview questions [1]
Question 1
“As an engineering professional, imagine you are tasked with designing a liquid metal siphon system to harvest molten neodymium from an electrolytic cell. Keeping in mind the specific engineering parameters, such as temperature, viscosity, and flow rate, could you please draft a detailed diagram showcasing the key components and their connections? Additionally, how would you address any safety concerns related to handling the highly reactive neodymium metal and ensure efficient extraction from the electrolytic cell?
This question has been thoughtfully designed to give the candidates the opportunity to showcase their grasp of engineering principles and innovative thinking. We encourage you to take your time and provide a detailed and well-thought-out response."
