BRAND: Saatchi & Saatchi

Experience Level: Management

Company description

We are Saatchi & Saatchi - a full service, integrated communications network, with 114 offices in 67 countries, with our headquarters in London. Saatchi & Saatchi is part of the Publicis Groupe, the world's third-largest communications group.

Saatchi & Saatchi launched in 1970, with the philosophy that "Nothing is Impossible" - a statement that crowns the top of our London building and is fundamental to our spirit. We approach things with the audacity of chutzpah. Chutzpah defines our culture at Saatchi & Saatchi. It's the quality of audacity. Because if you are going to attempt impossible things you have to have the audacity to believe you can achieve them.

It helped us build an agency we are really proud of and does things differently - which means an industry leading diversity approach, that includes Saatchi Ignite - our curriculum-based schools programme, Saatchi Open - our entry level programme, Saatchi Home - our affordable accommodation initiative, Saatchi Women - our programme for progressing talent, and Saatchi Family - our programme for parents and carers.

We are still looking for great clients. Still trying to rock the world. Still believing. Still being impossible. Still having ideas that make our clients famous. Still searching for people who want to set the world alight. Still knowing there isn't a problem a great idea can't solve.

If Nothing is Impossible is our spirit, then Chutzpah is what runs through our veins. But there is still one missing ingredient in creating the impossible and that's YOU.
