C'mon. I assume you are relatively young. But, here are the obvious answers:

1. I have tons of free time. But I am spending it with my kids and family or reading books. Sometimes I am going out with some old buddies.

2. You have no idea what level of technology or engineering I am using at my work. I could be programming microcontrollers or writing risk calculation for a bank. Both require same skill: attention, read documentation well, invent the solution, implement it and maintain it. That is a "strong" developer.

3. You better do following when I am seeking a job at your gig: invite me for a in person interview, tell me the story of your company, tell me the current pains, I tell you what can I do for you, how long I need and how much it costs you. If it matches then we have a deal.
