How difficult has it been to find another job during your career?

How difficult has it been to find another job during your career, both now in this job market and in the past?

I've always felt the semiconductor and electronics industry has been tough to switch jobs in. Even in the best of times, getting interviews was spotty, and it would take years to find another job with a different company. The only exception to this in my career was around 2005 when I was a student applying for internships (actually had quite a few offers then), and in the 2022 time frame when I got a few interviews and offers fairly quickly.
