• Sector research and events on ESG, VC and deeptech (including quantum computing commentary)

Quick Application Angles

• Reference the firm’s active VC and M&A credentials (Chambers Band 2 rankings and recent Series A / mid-market deals) and demonstrate commercial awareness of how venture terms (e.g. investor protections and participating preferences) affect founders.
• Showcase any direct start-up, VC or technology experience and explain how that exposure prepared you for client-facing transactional work at a firm that serves high-growth tech and impact-focused companies.
• Mention the firm’s sector work or publications you have read (for example the Term Sheet Guide contributions or MH insight pieces on quantum/AI/ESG) and use those to evidence specific commercial questions or learning points you took away.
• Highlight collaborative and training-focused examples (mentoring, team projects or CPD-style learning) to align with the firm’s emphasis on MH360 Academy, peer support and partner-led development. Trainee ratings for training quality and peer support are especially strong—use concrete examples of learning-by-doing.
