Ask HN: What are the biggest challenges in overseas developer job search?

Howdy everyone, Thinking about launching a web page with FAQ about finding employment abroad as a tech worker. In your opinion, what are the biggest "pain points" when it comes to international job search? What topics would you like to see covered? Some ideas: 1) International job search strategies. 2) What should a resume look like? 3) Why recruiters don’t respond. 4) How to succeed in an online job interview. 5) Salary negotiation. 6) How to pass a technical interview. Any feedback will be helpful. Thanks!
