Actuarial Interview Day
Actuarial Interview Day connects students and alumni with employers offering actuarial internships and full-time positions. As program coordinator, I help connect WCU candidates with this annual recruiting opportunity. Students and employers interested in participating are welcome to contact me at
jxu@wcupa.edu.
Fall 2026 participation snapshot
The WCU application records for the Fall 2026 recruiting cycle include 24 unique candidates and 98 distinct applications across 9 companies and 14 job postings. Applications are counted separately for each candidate and position. This snapshot reflects recorded applications, not interview or hiring outcomes.
Participation highlights are updated each fall semester.
For employers
I welcome inquiries from employers and industry partners interested in connecting with WCU students and alumni in actuarial science and financial mathematics. Please contact me about internships, full-time positions, Actuarial Interview Day, campus or virtual recruiting, guest presentations, mentoring, and opportunities for industry or research collaboration.
