I'll chime in. My RHCA got me almost nothing that the RHCE wouldn't have gotten me.
It took me ten months to find a new job. I thought the RHCA would almost guarantee getting a job quickly. Unfortunately, I found out that employers frequently confused RHCA with the RHCSA. A few times I was passed over for not having the RHCE. I had to explain that the RHCA is five exams beyond the RHCE.
A collegue of mine who went through most of the same training as I did didn't persue the RHCA due to my experiences. He saved LOTS of money and time.
I did learn a lot of stuff. Unfortunately, very little of it I used in my day-to-day duties. I got the following certifications: Virtual, Satellite 5, Debugging, Config Management (Puppet), Clustering. Of five exams, I *never* used Virtualization or Clustering. Satellite 5 was most certainly the most useful to me. We never used Satellite 6 with Puppet integraton (as it *stinks*). The debugging was useful, but not terribly so.
That being said, I've invested in the online learning not only to learn about other technologies but also to re-up my RHCA. Yes, I'm complaing about the RHCA and trying to renew it at the same time.
If you are in Linux path, Its better to have the RHCSA Certification. I had RHCSA in this year June. And Got a new job becasue of that. Its good. It teaches us very basic and everything that you need to know to go through in linux. Its the foundation and after having RHCSA , you can have RHCE too. After passing RHCSA it tends you to do RHCE. Do it. Its awesome.
I think RHCA is mostly for you. Employers don't really get impressed by it, because a lot of them simply don't know what it is. The knowledge is great, but if you don't use it, you lose it, as is the case with everything .
After getting RHCA, life went as before. I continued working at my position, and I feel much more ready and prepared for the world of containers. I got ready to play with Docker, and started using it in my life. I doubt it'll get me a job. Rather than getting you a job, it might get you an interview, where you'll have to prove your knowledge once again .
So that's why I think it's great if you do it for yourself, but won't yield much benefit if you want to get a job ASAP. In such a case, I'd choose my certs strategically, i.e. RHCE, OpenShift certs (since it gets you closer to Kubernetes), and various automation certs. From those, I think you get the most bang for your buck.
PS: People being confused about RHCSA vs RHCA is a real issue :/ Also, a lot of people don't know you don't have to be a RHCE to get to a RH architect. Another issue I'm afraid.
