I have questions to ask regarding CV,

if I have been working for the same company for the past 4 years, and I have been promoted several times, how should I capture the information under the work experience section? should I classify it under each company example

i -Company ABC (position Manager)

<description of role>

ii -Company ABC (position Team Leader)

<description of role>

iii -Company ABC (Executive)

<description of role>


or

should I compile it under same company

Company ABC

i -Position: Manager (Jan 2012 - current)
<description of role>

ii - Team eader (Jan 2011 - Dec 2012)
<description of role>

<description of role>


Which one is more effective?
