Timmy Tomkins You are correct. From the Helios accident report:-
Cabin Attendant number four (age 25) also held a UK Commercial Pilot License (JAR CPL A/IR) with an issue date of 2 October 2003, and valid to 1 October 2008. His JAA Class 1 Medical Certificate was valid from 15 July 2005 to 17 July 2006.
The accident occurred on 14th August 2005 some 22 months after he gained his CPL. He therefore had some twin prop experience and had passed an IR. I don't recall the job climate at the time but clearly he was still working as cabin crew 2 years after becoming employable as a pilot. He was keeping his medical up to date so presumably still job-hunting.
Notwithstanding his experience..... Helios' last RT communication was at 0620 passing FL290 for 340. The F16 pilot later witnessed a person entering the FD at 0818, some 2 hours later. That's a long time to be waiting to intervene.
