- Demonstrate commitment to the firm’s people‑first culture: mention interest in joining internal committees (diversity, wellbeing, charity) and give examples of relevant volunteering or event organisation to show cultural fit.
- Tailor applications to the Belfast/IPLS route: make clear you are (or will be) registered with the Institute of Professional Legal Studies and explain how your coursework and practical experience prepare you for a two‑year training contract with partner‑led supervision.
- Show practical examples of teamwork and client service (e.g. commercial internships, charity projects, pro‑bono work or part‑time roles) rather than relying on grades alone — Mills Selig emphasises hands‑on experience and client exposure for trainees.
