Are certifications worth it?
I have just been on RedHat SA 3 training course (4 days) and sat exams
EX200 (RHCSA) and
EX300 (RHCE)
The daft thing was that politics meant I wasn't allowed to take courses SA 1 or 2. So I learnt about stuff I would never use (SELinux; iSCSI; NFS Kerberos encrypted with user specific access rules etc.) and then took the exams.
Somehow I passed RHCSA for the course I didn't do, even though I didn't know a few big chunks so would score zero for those sections. Sadly I failed on RHCE because there's too much to remember about irrelevant stuff that I would never dream of using and it all seems a bit over contrived.
Given that the exams marks if you can pass the exam rather than how you perform in a real job, what do people think of it's value? It might look good to management and help get an interview, but as someone not looking to move, ........ ?
Just wondering,
Robin
