Experience Prior to stage 2, I worked as a health psychology researcher at UCL which REALLY improved my prospects during the stage 2 admission process. I'm also allowed to use experience gained from that position towards my health chartered psychologist training as I was crucially supervised by chartered health psychologists. I would seek out qualified chartered occupational psychologists via the BPS or HPC website and ask their advice and if possible, obtain work experience supervised by occupational psychologists.
Incidentally, I've got two support worker jobs to build my clinical skills in working with vulnerable populations. However, these positions are poorly paid (ie just above minimum wage) but are allowing me to develop some skills and such experience is increasingly relevant for graduate psychologists jobs, especially for the highly competitive assistant psychologist and research assistant positions.
Volunteering is a good way to obtain relevant experience. My stage 2 placements are voluntary positions with various cancer charities and NHS smoking teams. Looking to expand to academic health psychology departments, preferably at my old health psychology job department at UCL. Prior to stage 2, I volunteered as an assistant psychologist for several clinical psychologists which provided me with useful experiences and opportunities to network.
Look out for areas and organizations that occupational psychologist work in ie human resources, etc etc and try and obtain some experience there. Or maybe researcher or assistant psychologist positions specializing in business/organisational issues and work stress?!
Whilst I'm applying for graduate psychologist jobs (ie research assistant, research associate, assistant psychologist etc), given the crap job market at the moment, I'm also working on my publications to improve my employability and continuing with relevant placements to improve my prospects. I'm hoping my completed PhD will improve my chances in a very competitive psychology graduate market.
Best of luck
