 Estimate size of vehicles fleet in a large city3 AnswersTried to approach problem using bottom-up reasoningThis is a simple market-sizing question. Therefore you need to make assumptions on the numbers, for example... Assume large city = 5 million people Assume 60% own a car, the rest use public transport = 3 million people Assume 50% of these people work in an office = 1.5 million people Assume 10% of these people are middle to top mgt = 150K people Therefore size of the vehicles fleet in a large city = 3% of population of the city This is an example of how it can be done. They are not looking for the exact number! They won't to know how you think...how you break a problem down."Define" large city to mean 10 million people+, but assume 10 million to keep the math feasible Assume that those living under the poverty line cannot afford cars - this takes 30% or 3 million people out of the running Out of the remaining 7 million people, assume that 30% are under 18 and another 20% are over 65 and thus are unlikely to drive a car themselves This leaves a potential car-owning population of 3.5 Million people Assume that there are 2 types of cities - ones with great public transport (e.g., NYC, San Francisco) and others with poor public transport (e.g., Dallas) In the former, only about 20% of the potential car-owning population is likely to hassle with owning a car, but in the latter 70% of the potential owners may opt for a car. Thus the range of cars that I'd expect to see in a city of 10 million is somewhere between 700K and 2.45M. Oh and by the way, I am assuming that this is a city with enough infrastructure (e.g., roads, parking, gas stations) to support cars for this many people.

 Describe a situation in which you resolved a personality conflict in the workplace.2 AnswersThis is the question that I found most difficult to answer - I really haven't ever had to do this.if you dont experience that, better to answer frankly. and then provide your thoughts on this: to ask someone with more experience for advice (including your senior/ team head etc who have no direct personality conflict) and leverage the advice. business to business, no personal emotion involvement to handle the work

 Should one company purchase another company that is in a very different field? 2 AnswersNo financial information was given and very little information given about either company yet the session leader expected an exact answer.It all depends on whether there are aspects / pieces of that company that fit with the core competencies of the purchasing company. Starbucks buying Exxon gas stations would be a good fit since they can sell their products in the convenience stores associated within each Exxon gas station. However, Starbucks purchasing an oil and gas drilling company probably wouldn't make much sense. It's all about whether synergies can be created between the purchaser and purchasee.
