This question is to judge whether one is aware of the environment of the agile way of working. Here the answer is expected to cover few or all of below:
The traditional way is sequential where design-> Development-> Testing etc. happen one after another whereas in agile all of this is done in every iteration/sprint
Changes are welcomed in agile as Scope is flexible whereas in traditional manner scope is fixed in the beginning due to which changes have to follow change request path
Progress is measured with % completion traditionally whereas working software is the measure of progress in agile
Project Manager as a central controlling authority is traditionally driving the project whereas Self-motivated and self-organizing teams drive the projects in agile.
