How do you advertise yourself or how can companies find you? I'm asking because I found Eastern Europe to be surprisingly underrepresented on the hiring websites that I use.
Well I don't advertise myself at all. I am searching for companies that are hiring remote employees and they don't have requirement to be located in US. I'm using remoteok.io, jobs posted on hackernews, some combination of googling and friends' recommendtions.
Any job you see posted on the internet is seen by many many other people around the world. It probably attracts thousands of resumes. This means most of the 'hiring' process is finding ways to reject resumes quickly to make the numbers manageable. Suppose there are 1000 applicants and 100 of them meet the requirements. Ten of them get phone screens. Three get an on-site. One gets hired. 1000 applicants is optimistic. It is probably several times. Particularly for a job listed at an aggregator. If it's easy for you to see a job, it is easy for thousands of other people.
