DS, currently a postgrad student, has an interview tomorrow for a place on the graduate scheme of a large multinational. If he were asked one of those typical questions such as "tell us about a situation where you have successfully dealt with adversity" would it be inappropriate to use the example of how he faced a chronic illness (which counts as a disability under the Equality Act) whilst an undergraduate and came out with a good degree? He is otherwise in very good health (no one would know there was anything the matter with him, his life expectancy is now normal and his energy levels and general health etc. are normal).
Obviously, if he were offered the job, he would have to declare the illness on any health checks.
