OCS and You
Office of Career Strategy
The Office of Career Strategy offers a variety of services to help students prepare for industry jobs--including but not limited to setting up Yale-coordinated internships, resume review, mock interviews, and career advice. Drop in at OCS on a day while classes are in session or visit their page for more information.
OCS is best for general questions about the job/internship search process, but for tech internships, the recruiting timeline and coding interviews are very different from the requirements for most internships. For more information about tech career advice, feel free to reach out to DSAC or do your own research.
Career fairs
There are a variety of career fairs relevant to CS majors held at Yale throughout the year. In the past, a diverse set of companies involved in everything from online payments to financial security have had booths at these fairs; repeat attendees include Google, Facebook, Microsoft, MongoDB, Palantir, and lots more. News about career fairs usually spread via email, so students should definitely subscribe to the mailing lists described above.
There are career fairs both for standard software engineering internships as well as more specific, niche pursuits. In the past, there have been CS career fairs for social good, healthcare, public service, engineering, and more. There have also been virtual career fairs (in which students can "attend" online) held by public and private sector entities alike.
SEAS resume book
The School of Engineering and Applied Sciences compiles an online book ofresumes from across Yale University--there are resumes from undergraduate and graduate students alike, and students can use it to get ideas for how to format their own resumes as well as get in touch with other students who have had work experience with particular companies.
