Prior to that I got interviews via Linkedin.
For small companies I look at https://angel.co . I have gotten interviews from there.
I got a job a few years ago from my local Craigslist.
If you go to Google and type jobs, it opens up their thing to look for jobs.
I got a consulting job from this (HN) website's who is hiring who is looking threads once.
I switched my IT specialty a few years ago and was just happy to be getting paid a few years ago. As I have been getting more experience, I have been looking at https://levels.fyi and have been looking at not only companies and cities, but even what positions are getting paid. I will probably move to a larger city for my next job.
