Hi Anonimous A
The cover letter is very important because of 2 main things:
- HR recruiters use it as an information source on your carreer path, motivation and willingness to be a consultant within their firm (and this becames crucial, when there are some gaps or unstandart situation inside your CV such as unusual job positions, not very clear shifts between employers or not correllated education)
- Interviewers do not often but still read your CV mainly for better understanding of who you are and what questions you to ask. CV also shows them your desire to get into the company and your ability to structurally communicate the most important information about yourself
Of cource your CV is not the most important part of the whole selection process but when correctly composed - it could help you a lot to land your dream job in consulting!
Hope it helps
