The job description of consultant covers a wide variety of business and service sectors such as recruitment, finance, advertising, PR, management, sales, human resources, IT, medicine and much more. In general terms, consultancy is simply dealing with clients or customers who need advice or assistance, however specialised. Working in partnership with clients to identify and provide for their needs is the key function here.
Positions as consultants occur at all levels, from entry to senior, but all require first-class communications skills, an analytical mind set and a thorough knowledge of their area of expertise in order to identify exact needs either within company departments or with individual clients in the public or private sectors.
Consultancy-level positions require either a qualification from an industry body or specialist course provider, with a degree in a related subject mostly mandatory. The more experience in the sector an applicant can demonstrate, the better as regards acceptance at a good salary
Consultancy salaries vary according to experience and the level of the position offered. IT and banking sector jobs commend good salaries and management consultants enjoy some of the highest salaries and benefits in the sector. For example, recruitment consultant salaries average from £29,000 upwards.

Employers will also be checking your grades whether you did well in school or not. Grades matter a lot. If you’re a holder of a postgraduate degree that could help too but not necessary in initially getting you hired as a management consultant.  Eventually, as you gain more experience in consultancy, your postgraduate degree will now begin to matter as you aim for a position higher up the corporate ladder.
