Here's my somewhat similar situation and experience so far.

Was in 3 startups as CTO in Beijing, China for a total of about 5 years. Two folded and the last one took off. Then decided to move with family back to the USA (Bay area). Have been looking for a job for three months.

Except for google, the large companies did not even respond.

Mid sized companies - things go well up to and including technical screening. Then, a wall is hit with the hiring manager and I get a "will not be proceeding to the next step" email. I'm 52. So, age may have a part in it.

Small companies and startups - better response, but usually they dont know what the hell they are doing.
