Elevator maintenance interview questions

A competitor offers to sell you [200] maintenance contracts, many on older proprietary equipment spread over a wide area. How do you decide?

Situational · Buying maintenance portfolios

Strong answer

Checks contract terms and renewal dates, equipment condition, access to parts and diagnostic tools, route density, mechanic capacity and retention risk, and prices it on margin, not revenue.

Tell me about a time you had to fill a superintendent or service manager role when few people in your area had elevator experience. What did you look for?

Behavioral · Hiring leaders in a scarce trade

Strong answer

Names the must-haves, such as code knowledge, credibility with licensed mechanics and customer skill, how they tested for each, whether they grew someone from inside, and how callbacks or renewals changed.
