Freelancers do no tech interviews?

When I did freelance work, it was all about connections and reputation. "Hey we got some problems with our overnight processing, you've done that before" type stuff.

They do some, but I find it more of a formality once you build a track record. The risk is lower than a full-time employee.

Not often, I think I only had one in the time I was freelancing, networking is everything.
