Does your family member have any particular field they want to work in – mammal conservation, fisheries, engineering projects, research etc?
In general, conservation or wildlife focussed jobs can often come from volunteer roles – even if not directly, this type of involvement “keeps your hand in” following graduation.
Depending on what line of work they want to go down, job hunting may need a different approach (consultancy vs. research for example) but the MBA, CIEEM and even IEMA would be worth checking out as professional bodies who will offer advice and graduate membership which might help them make the jump from student to professional or stay clued up to new opportunities.
Best of luck to them in any case,
