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 a synthesis that didn't work for months. How did you get it to work, or decide to stop?
What they are checking: How they handle persistence and judgment in hard synthetic research.
Tell me about working in a multidisciplinary team. How did your work connect to others'?
What they are checking: Whether they collaborate well with scientists from different backgrounds on a shared program.
How would you explain why chemical recycling matters to someone outside chemistry?
What they are checking: Whether they can communicate research clearly, which the posting lists as a key duty.
What would you do
Your new recyclable polymer has great recycling yields but weak mechanical properties. What do you do next?
What they are checking: Whether they can balance properties and recyclability instead of chasing one number.
A kinetic result contradicts a mechanism your team has proposed. What do you do?
What they are checking: Whether they follow the data and raise it honestly, even when it is inconvenient.
About the work
What design features make a polymer chemically recyclable back to monomer, and what tradeoffs come with them?
What they are checking: Whether they understand ceiling temperature, thermodynamics and the balance between stability and recyclability.
Walk me through how you'd study the mechanism of an organometallic catalyst using reaction kinetics.
What they are checking: Whether they can design kinetic experiments to tell competing mechanisms apart.
How do you evaluate the thermomechanical properties of a new polymer, and which tests matter most?
What they are checking: Whether they know DSC, TGA, DMA and tensile testing, and what each tells you about real use.
How do you handle air- and moisture-sensitive organometallic compounds safely?
What they are checking: Whether they have real glovebox and Schlenk line skills and good safety habits.
Which characterization techniques would you use to confirm a polymer's structure and molecular weight?
What they are checking: Whether they know NMR, GPC and related methods and their limits.
