1) Don't put your 30 years of experience on the resume, put what is recent that is relative to the job. Nobody really cares about what you did 20 years ago. No need to put your dates on your education either. They may see that much experience and think they can't afford you also. Keep your resume to 2 pages.
2) Most companies now have automated filters on their applications, it is looking for keyword matches based on the job description and your resume. Take the time and customize your resume for every job you are applying for.
3) Try to ensure your resume highlights tangible business outcomes that you have driven. Increased ad clicks by 30%, increase sales lead pipeline by 10%, streamlined processes, introduced new functionality, etc.
4) Network as much as you can on linkedin. Find old colleagues, friends, etc. Find who they are connected to when you are applying for a job, referrals mean a ton.
Most companies now for remote job have an interview with the HR person, then pass on to the manager, then interview with either a panel of 3-4 people or 3-4 people separately.
