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.

Committed to fostering technical excellence and professional growth in the architects and specialists you work with, and with the confidence to influence and advise senior civil servants, you’ll be a skilled user of Terraform, CloudFormation, Azure Resource Manager, Ansible, Puppet and Chef, and have expert knowledge of VMware and Microsoft infrastructure technologies. When it comes to academic qualifications you should have a degree or equivalent experience in Computer Science or Information Technology, expert or professional level certifications in relevant specialisms, and hold or be willing to work towards qualifications such as TOGAF, ITIL, Agile Project Management and PRINCE2.
