If you are applying for 40 remote jobs in one week, but you’re not getting responses, you have a problem.
Firstly stop looking for remote jobs. Look for the skill you can offer, then use filters to find remote-friendly jobs. In your profile describe how you can work independently - mentioning any written skills, asynchronous tools and successes you have achieved alone.
Look at a proper board with good filters (such as remote jobs on Kaam Ki Khoj) and read through each job description carefully. Real employers will never ask you to pay. Apply as early as you can, be polite with your follow up and keep track of your applications in a simple spreadsheet. Being consistent is always better than luck!
