Finding jobs are not easy. My brother has a master's degree and did time in the navy. He's excellent with data, management and technology and he's been in and out of work for years. There is really no job that's fast to get and earns decent pay unless it's shady. You have to put your resume on a job site like Indeed and let the jobs come to you.
Your brother was over qualified for the jobs...that's what I was always told when applying for jobs.
I did the online resume thing with Indeed and other sites after I lost my job to outsourcing. Never got a hit. Guess I was over qualified on those too. Or maybe it was my age.
Amazon Turk is something you might be interested in but you have to bid for jobs. I'm not good at that.
I always loved to do research. I used to do inventory control for a company and I loved it. Then i left to get my business up and running. I used to do legal patent and trademark work for an attorney, researching if a patent or a trademark was already owned by someone else, typing up the legal briefs for patents and trademarks, etc. I also did medical transcription at home plus worked for a local hospital and a national service. I loved both until the outsourcing took over the medical end. Sadly, my attorney retired because of illness (after 28 years). I miss doing that. Medical transcription isn't worth it anymore. They have lowered the cents per line, upped the amount of work needed to do to earn decent money, and the quality has to be around 100% for American MTs but not the overseas people. Plus speech recognition has overtaken real transcription and that's why the lower rates (and SR really sucks. it's awful, too many errors in it). You also need to take the course and there's only one course most companies would hire you from and they're expensive.
As for me, I've finally given up looking after 7 years. I decided that I have too many marks against me ever working again.
