Looking for advice on job hunting in recruitment with 15+ years of experience—it’s been quite frustrating!

Hey everyone, this is my first time posting here, and I’m feeling pretty desperate and frustrated. I’ve spent the last 15 years in IT, finance, and executive search roles, and in the past couple of months, I’ve applied to over 500 jobs without any success. I’ve consistently been a high performer and have held management positions, but even with a solid network, I’m struggling to make progress. I’m located on the East Coast of the US. Any advice would be greatly appreciated. Thank you!
