I'm a Chartered Psychologist and Associate Fellow of the British Psychological Society (BPS). I am also Vice Chair of the Association for Business Psychology (ABP) - the professional body in the UK for business psychology which seeks to maintain and develop standards of excellence for the profession. For over 20 years, I've worked in investment banking, strategy consulting and as a freelance consultant helping a range of large private and public sector corporates recruit, train and manage their employees. Whether designing simulators to select foreign exchange traders through to assessing leaders at board level, I know from experience that observing people doing a role is more informative and powerful than hearing people describe what they claim they can do. I've introduced internships and assessments which feature realistic job previews because I know no one wants to apply or work in a job they can't do - and therefore won't enjoy and will find stressful. In short - I have personally found and all the academic and peer reviewed research will back up the fact that giving people better insights into roles they are applying for helps them make better decisions for themselves.
