<p>Normally how long do summer internships last?</p>
<p>3 months, usually from the beginning of June til mid to late August. Sometimes hedge funds only need people for 5 weeks because people go on vacation so they need extra help.</p>
<p>Usually 10 weeks</p>
<p>Formal investment banking summer analyst programs are typically 10 weeks.</p>
<p>10-12 weeks seems to be the standard length, although a friend of mine was able to get his down to 8 (though he let them know AFTER he got the job).</p>
