I think the full-time Essex MBA is a bit of an afterthought compared to the online MBA and apprenticeship MBA. The programme's vibing off the growing numbers of applicants with an interest in sustainability and CSR and, as at Liverpool, the online MBA has the potential to generate profiles that can support scholarships and good research-active academics. Despite student supply, employer demand is limited in that CSR niche that Exeter and Bradford have already struggled with.
Furthermore, Essex's MBAs don't have dedicated careers staff and, indeed, I understand that students use the central university Employability and Careers Centre, which has 16,000 students to support for internships, events, part-time students jobs etc.
PS I think the MBA profiles are pretty instructive.
