## Source excerpt

It's the end of another dev internship season, and this one marked something of a transition, since halfway through the season, NY-based interns were invited back to the recently reinvigorated office. Which means that many more of us got the chance to meet and hang out with the interns in person than we did last year. And hopefully the interns were able to get a better sense of Jane Street and how it operates.
