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
How do you hand a completed installation over to the people who operate it?
What they are checking: Whether they hand installations over properly, with training and documentation, so operators can run equipment safely from day one.
What would you do
A pilot plant runs changing processes rather than one settled one. How do you design equipment for that?
What they are checking: Whether they design equipment flexibly for changing processes, since a pilot plant rarely runs the same chemistry for long.
You'd provide technical support to the plant alongside the projects. How do you balance project work against a plant that needs help today?
What they are checking: Whether they can balance project work with urgent plant support, which is the dual responsibility built into this role.
A campaign is running and your project needs a shutdown. How do you get the window?
What they are checking: Whether they can negotiate shutdown windows with operations respectfully, planning work around campaigns without disrupting critical production.
How do you scope a small project so it does not quietly become a large one?
What they are checking: Whether they define and control scope carefully, so small projects do not quietly grow into large, expensive ones.
This is at the North Chicago pilot plant, alongside a set of larger transformation project roles on a strategic capital project. Why the pilot plant seat?
What they are checking: A real reason for this work rather than the bigger project
About the work
This role runs small to medium capital projects for an active pharmaceutical ingredient pilot plant. What pilot plant work have you done?
What they are checking: Whether they have real pilot plant experience, which differs from commercial manufacturing in flexibility, scale and how processes change.
What is different about a pilot plant compared with a commercial plant, from an engineering standpoint?
What they are checking: Whether they understand the engineering differences of a pilot plant, such as multipurpose equipment and frequently changing processes.
Walk me through a capital project you took through the full life cycle.
What they are checking: Whether they have taken capital projects through the full lifecycle at this scale, from scoping through installation and turnover.
What safety considerations are specific to pilot-scale chemical work?
What they are checking: Whether they understand process safety in pilot-scale chemistry, where new reactions and changing materials create unfamiliar hazards.
