Social Impact and Sustainability

It is in line with our core values – excellence, integrity and supportiveness – to consider the impact of our business within wider society, and our potential as engaged citizens to contribute meaningfully through partnerships and pro bono work.


We recruit curious, quietly confident people at all career stages.

Regardless of whether you are looking to join us straight after graduating from a top-tier university or business school, move across from another leading consultancy or transition from industry, we offer interesting engagements, rapid progression and industry-leading career development.

We employ inquisitive self-starters so that new joiners can make a significant contribution to projects and solve client problems from day one.

We are committed to building an open and diverse workforce where individuals from all backgrounds can thrive. We also have a strong focus on social impact and sustainability.

CIL’s vibrant alumni programme strives to support our colleagues throughout their careers, providing them with access to exclusive events, career advice and mentoring opportunities.

  • Strong team working and people skills.
