How subdivided were wooden British warships?

Were East India Company ships as compartmentalized as purpose-built warships?

They were about as subdivided as contemporary British warships, which had little compartmentalization and could remove internal partitions for action. More extensive subdivision is associated with the later iron-ship era.

East Indiamen and the British wooden warships used for comparison both had relatively open interiors. HMS Victory illustrates how partitions could be taken down for action and stowed below to free space for the guns. The move toward extensive compartmentalization is associated here with the later age of iron construction. HMS Warrior and the monitors are subsequently used to identify that era. This comparison concerns these ship types; the following discussion of Chinese junks shows why it should not be treated as a universal claim about wooden hulls.
