Interested that you feel its helped your career, Ghengis. I am at the narrow end, (graduate engineer, done placements, struggling to get grad training), and tried to get some pointers from their careers service. Result was a curt letter telling me to buy Flight every week.
I joined as a student (have been upgraded to graduate) mainly with eventually getting chartered status in mind, but was a bit disappointed with their showing on this.
I'd be interested to hear your thoughts on how membership benefits career path.
Regards, BGPM.
