two questions regarding top MBA

<ol>
<li><p>where do most people with undergrad engineering degree work after graduation to prepare for top MBA? i know consulting firms and stuff is ideal but those don seem to fit the engineering degree or does that not matter at all?</p></li>
<li><p>what kind of EC activities during college to best prepare for top MBA?</p></li>
</ol>

<p>Thank you</p>
