Mechanical Engineer Intern I Interview(Student Candidate) Bossier City, LA

We were sitting in the third floor of a 16 floor building

 . After asking me about my experiences with working within a group the interviewer suddenly asked me, "How many pennies would it take to stack as high as this building?"

It took me a second to realize that his apparent non sequitur was an attempt to evaluate my problem solving capabilities and methodology. Then, I estimated the width of a penny and the height of the floors within the building and talked through a calculation for him.

It would be one penny less than those which would just exceed the height of the building when stacked above one another.
