I completely understand the question, and I've asked myself the same thing before.
In my case, I see certifications and recertifications as useful tools, especially to stay current. Genesys Cloud is constantly evolving, with weekly updates, and it's easy to miss some changes over time, especially in areas we don't work with every day.
When studying for a certification, we usually have the official exam guide, but also several additional trainings by module, as well as the Resource Center. Going through those materials helps me review the platform, close knowledge gaps, and catch up on topics or updates I may have missed along the way.
At the same time, I don't see a certification by itself as proof that someone is an expert. To me, it shows that the person has a good foundation and understands the main concepts, but real expertise comes from hands-on experience, troubleshooting real scenarios, working with customers, and applying that knowledge in practice. So I do think certifications are valuable, but I see them as a complement to experience, not a replacement for it.
That said, I think the biggest challenge is time. I usually study during my free time, and that's a personal choice. If someone doesn't have much time available, I'd probably recommend focusing first on the core certifications, such as the Professional certification, and then on the specialties that are most relevant to their current role or career goals. After that, if they still have the time and motivation, pursuing additional certifications can still add value.
Another important point is how much you actually use that knowledge. If you get certified in an area that is not part of your day-to-day work, there's a good chance some of that knowledge will fade over time. That doesn't mean the certification has no value, but it does mean you may need to be intentional about revisiting that content.
So I don't think there's one right answer. For some people, fewer but more strategic certifications make the most sense. For others, especially in support roles or roles that touch many parts of the platform, maintaining a broader certification path can be very valuable. That being said, I see additional certifications as valuable, but not necessarily mandatory. It really depends on your role, your goals, your available time, and how much value that certification brings to your day-to-day work.
