I did consider applying for a role in a very similar field, but figured I'll be fighting an uphill battle with no knowledge in trading/stock market/etc.
but that story is not the most efficient way (although I do talk about a better approach at the end).
To summarize:
A LOT of hedge funds hire non finance people for specific roles e.g. cloud, Linux tuning, networking etc
The smarter ones have realized that there are great people everywhere e.g. Gaming company SREs have a lot of relevant experience due to high traffic load, short SLAs and lots of financial risk due to outages. Applying for a role in one of those departments is a lot easier than trying to jump directly into a trading desk/operations role.
Finally, knowing someone on the inside also helps a lot which is made MUCH easier by LinkedIn, Twitter etc
Now, I'm not disqualifying them if they dont read the journal. But if they can't demonstrate any proactive interest in finance, or tell me about some happenings/events/stories they personally find interesting (theres a ton of interesting stuff happening) its definitely an amber flag.
