Graduating senior mathy summer opportunities

<p>I’ve come across a ton of stuff that’s available either to only rising high school students or to only undergraduates. So, I’m interested in what people have found both interesting and available in the past.</p>

<p>I’d prefer some sort of internship or work experience (in finance or tech or something) to pure research, but if people have had cool experiences in some research program, I’d love to hear about that, too.</p>

<p>Thanks!</p>
