Career astrology is a branch of astrology looking at the Midheaven (MC). 
The MC is the zenith of a chart, and designed to note the highest potential of a native.
As a rule of thumb, each MC sign lends to various potentials:
Aries – leadership
Taurus – leadership/command
Gemini – relationships/communication
Cancer – caring/protection
Leo – leadership
Virgo – administration/organisation
Libra – communications/interrelation
Scorpio – control/command
Sagittarius – Learning/faith/higher truth
Capricorn – administration/organisation
Aquarius – change/technology/new ideals
Pisces – help/benevolence/development
These are generalisations of course, though MC placements do greatly shape career potentials.
After this, the personal planets, aspects, and other points are noted.
So, does a natal chart lie?
In my experience, no.This isn’t hyperbolic, but I’d imagine every human alive has an accurate natal chart. This is in terms of career potentials, and personality traits. Some charts ‘scream out’ career placements. Take President Obama. He has a sixth house Sun/Mercury, Scorpio MC, and Pluto/Uranus in 7th house. Clearly then, work, duty, strong speech, changing relationships, and command/control are prominent in his professional and personal lives.
It’s interesting to note that the natal chart impels, but doesn’t compel. This isn’t a cliche, though energies can be used in differing ways. President Obama could well have been an academic, a CEO of a large firm, or some other form of thought leader or chief spokesperson of a body. However, his natal placements do…well impel him to these specific roles. In life, we may have various non-fixable circumstances, though choice always exists in these contexts. 🙂
