Competition for graduate vacancies is often fierce, so an internship can be a boost for your application. Employers are looking for very specific skills and attributes in applicants to their firms. And perhaps nowhere more so than in Consulting. Some of the skills required are; 

• Commercial awareness 
• Good numerical skills 
• Attention to detail 
• Analytical skills 
• Excellent interpersonal skills 
• Tact and persuasive ability 
• Team-working skills 
• IT skills 
• Good oral and written communication skills 
• Self-motivation

Foreign language abilities can also be useful.
