These are invitation-only events that bring together companies with African talent from the international market.  The Summits enable a consortium of leading companies to interview pre-selected candidates.
Summits are held across the world- and one is held in May in London. Although the Summit is in May,  the application deadline to attend is very soon:  28th February 2013.
More information can be found on the Careers In Africa website.

Note: All applicants to attend MUST have an excellent academic track record and work authorisation for at least one African country.
