Recently my wife and I were musing about my checkrides, so I went through them. My private endured loneliness for about 15 years before I added SES (single-engine sea) to the certificate. Those two hung out together on my paper certificate for about another 15 years as I was mostly a dabbler, flying when time, money, and obligations permitted. Then, my certificate enjoyed a flurry of changes over the next few years as I added an instrument rating, commercial, multi, and finally all three CFIs.
A few years later, the airline I’d joined after dumping my high-tech career, paid for my ATP. So, I’ve had nine checkrides. I remember some and have forgotten a few. But, there are stories.
