let's say the cu stat had 100 chinese people and then if a job is posted then 60-70 of them will apply for it. So could you please tell me that is it possible that 60-70 all had interview, besides you didnt count ieor 200+ people and other department.
Actually i can tell you one thing, last year High Bridge Capital management( the biggest hedge fund in the world) had a entry level job post at columbia, after several days it was deleted and repost but add some thing in the job title( only for undergraduate), because thousands of chinese master students apply for it. HR for HBCM is crazy. Since then, columbia career center set requirements in the system, if a job require undergradute, and you are master , you can not apply.
