About your past

Why are you interested in a chemical engineering co-op in industrial packaging?

What they are checking: Whether they can connect coursework to practical problem solving, which they will need on site.

Tell me about a time you had to learn a new tool or software quickly for a project.

What they are checking: Whether they can ramp up fast, since a summer co-op has little time to get productive.

Tell me about a time you worked on a team where someone was not pulling their weight.

What would you do

You are given a project but the goal is unclear. What do you do?

What they are checking: Whether they ask good questions early to define the problem instead of working on the wrong thing.

How would you present the results of your summer project to plant managers?

What they are checking: Whether they can communicate technical findings clearly to people who care about cost and results.
