My answer was suitable for "doer" type of personality, but what was expected is an "analyzer" kind of answer. I mean my answer was short - don't take upon more that you can do, but what they were looking for is the description of whole process how do I get there -creating a list of projects, assessment of suitability/ profitability /urgency, ranking from best to worse, allocation of resourses, etc. etc. I should've answer with another question - do you want results first and then the process or vice versa? This would help me to customize my answer to the interviewer.
