Working closely with colleagues across the business, you will help develop innovative, data-led audit methodologies and solutions that continue to enhance the department’s data science capability. You will also support the delivery of the Internal Audit strategy by sharing your technical expertise, developing colleagues’ data analytics skills, and carrying out technical reviews of data insights work.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
