Graduates don't get assigned to any particular industry group, they are aligned to the Competencies/Service Lines (Strategy & Operations, Technology Integration, Enterprise Applications or Human Capital) - the "verticals". The TMT sector is one of the key Industry Groups - the "horizontals" in a matrix organisation, if you like. If you're keen on TMT, I'd recommend reading about the three industry sectors that make up the group on the company website and try and relate the information to your experience and/or career objectives.Best of luck to you both.
