Basically, one thing: I don't have eight years experience with Kubernetes. (Hint: Kubernetes hasn't been around for eight years.) Recruiters and resume-reading algorithms don't know a good candidate when they see one; they look for unrealistic numbers, a la "someone aged 24-26 with 30 years experience", without ever knowing they're looking for a candidate who doesn't exist.
Otherwise, they decide to 'move forward' with other candidates instead because of some niche experience that you happen to lack by sheer chance. It's news to most non-programmer hiring staff that a C++ expert is capable of getting up to speed on Java in their first two weeks on the job, or that a React developer is capable of picking up Angular over lunch.
My experience (10 years running my own company) has never been a problem in and of itself. If you can create and ship software, even in open source, you're generally "good" (barring the above).
Please recognize that the applicant screening process is broken beyond the point of usefulness. The "front door" doesn't work for virtually any company. Get into open source, network, meet people, and get in the back door via referrals. That's about the only way to land a job anymore.

It's a windy road, where the goal seems to get lost on the way, but your advice makes sense for anyone that can stick to the difficult path.
