The 3.6% figure was from the class of 2017. My post mentioned that other colleges besides that are top ranked in CS with public post graduation reports follow a similar pattern, including those reporting for the class of 2018. A similar list of companies are most represented at CMU, MIT, Berkeley, and others. These companies include “software engineer” at Google, Facebook, Microsoft, Amazon, …; and fintech positions are rare (but not necessarily zero). If you step down to slightly less than top ranked CS colleges, then there is often a strong bias towards software engineering type positions at local companies rather than SV, but again not fintech.
Lets try this a different way. Is there any post graduation outcome report for any selective college in the United States that indicates that shows a different pattern in which the referenced fintech jobs are not rare among any grouping of CS majors?
