Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about your industrial experience with plating or solution-based processing. What did it teach you that research didn't?
What they are checking: Whether they bring practical, scale-minded experience the posting specifically asks for.
Tell me about a time you wrote a technical report or paper that changed what your team did next.
What they are checking: Whether they can communicate results in a way that has impact, as the posting expects.
Why does decarbonized metal production matter, and where do you think electrolysis can help most?
What they are checking: Whether they understand the bigger goal of the work and can think about where to focus.
What would you do
How would you think about scaling an electrolysis process from bench to something industry would use?
What they are checking: Whether they consider energy efficiency, cost and durability, not just lab results.
Your deposits come out powdery and poorly adherent. How do you troubleshoot?
What they are checking: Whether they can reason through current density, mass transport and electrolyte chemistry.
About the work
How do the challenges of electrodepositing a metal differ between aqueous, non-aqueous and molten salt electrolytes?
What they are checking: Whether they understand the electrochemical windows, temperatures and handling problems across electrolyte types.
How would you measure physico-chemical properties like conductivity, viscosity and density of a new molten salt electrolyte?
What they are checking: Whether they know practical methods for electrolyte characterization, a key part of the role.
What role do additives play in electrodeposition, and how would you test whether one helps?
What they are checking: Whether they understand how additives change deposit quality and how to evaluate them systematically.
Walk me through how you'd use cyclic voltammetry to study a new metal deposition process.
What they are checking: Whether they can design and read electrochemical analysis experiments.
What safety steps do you take working with molten salts at high temperature?
What they are checking: Whether they take high-temperature and corrosive hazards seriously in the lab.
