Too early to think about becoming a CEO. Join as a fresher, put in hard work, learn your job, contribute to the organization, perform beyond the expectations of your managers, find out how others perceive you, add to your learning profile by doing some on-line training programs etc... In brief, climb one step at a time & introspect. Improve your profile as you climb up, you may realize there is far too much to learn, not only about yourself but how to manage people. Select the best manager in the organization as your mentor & learn through interaction.
Good to notice your ambitions, but as a sensible person plan to reach there. Remember: "Heights by great men reached & kept, were not attained by sudden flight; they, while their companions slept, were toiling upwards in the night."
