What does it take to be a top CEO?

That defining characteristic that singles you out as a leader is something that cannot really be quantified.

A heady mix of charisma, intellect, compassion and inspiration is surely a recipe for success – but how can you really judge who has what it takes and who’s lacking?

A recent study by Heidrick & Struggles, reported by City AM, found that top tier CEOs in the UK tend to have a background in finance, hold an MBA and be in their early 50s.

The report also highlighted that these Chief Executives tend to have been promoted from within, rather than being hired externally.
