What kind of gear do you use?

A question like this one helps the employer better discern your type of work style. People have their preference with which type of photography they choose. The same applies to the equipment that they use. This question won't stop an employer from hiring you unless you aren't using any equipment at all. That scenario will create the appearance that you are not engaging yourself prior to securing a job. Ideally, you want to share what gear you use and how. This indicates that you are engaged prior to and while working a job.

"Recently, my camera of choice has been Leica Q-P digital camera. I've been using it to take photos of architecture and people. For the most part, this camera has worked well for me with natural lighting. When I do need extra lighting, I make use of Leica's Flash and LED light. "
