Congrats on your OSCP - I run a cybersec biz and some of my colleagues have that cert and I’m always impressed when I hear someone has it. I’m a CISSP but I think an OSCP is more practical.
Ham radio extra which is elec eng focused rather than just rules of the airwaves is a good one. (I’m callsign WT1J)
In our biz I really appreciate it when folks have a Network+ or Security+ or a Linux admin cert because you can’t argue with the value of knowing networking fundamentals and the Linux command line. In fact knowledge of Linux command line is my leading indicator of competency for a QA role we have open. I look at answers to this question first every time. Next thing I look at is SQL knowledge- because I think both of these are strong predictors of deeper technical capability.
Certs are underrated IMHO because most of them provide practical knowledge that is immediately applicable in a work setting or other pastime. They give you real skills.
Lastly AWS certs are also super practical and very valuable IMO.
Great question OP!
