Example questions or scenarios:

• "Walk us through the most significant technical hurdle you faced during this research and how you overcame it."
• "If you had an unlimited budget to take this research to the next level, what would be your first step?"

Behavioral and Personality Assessment

Hexcel values "innovation with discipline." They want to know how you work within a team and how you handle the administrative and collaborative aspects of a scientist's role. This includes your future career plans and even practical matters like your visa status or location preferences.

Be ready to go over:

• Future Aspirations – Where do you see your career heading in the next five years within the composites industry?
• Conflict and Collaboration – How do you handle disagreements with colleagues or stakeholders regarding technical directions?
• Strengths and Weaknesses – A standard but vital check on your self-awareness and areas for growth.

Example questions or scenarios:

• "Describe a time you had to pivot your research strategy due to unexpected results."
• "What specifically draws you to the aerospace and defense sector over other chemical or materials industries?"

Technical Domain Knowledge

Beyond your presentation, you will face direct questioning regarding polymer chemistry, materials science, and testing standards. Depending on the location (such as Decatur, AL or Duxford, England), the focus may shift between carbon fiber production and resin formulation.

Be ready to go over:

• Polymer Characterization – Familiarity with DSC, TGA, DMA, and other relevant testing methods.
• Composite Manufacturing – Understanding of prepreg, infusion, or carbonization processes.
