I have been providing feedback and sharing experiences with people interested in applying for graduate programs in philosophy. Besides serving as a mentor at the Rutgers Mentorship Program for Undergraduate Philosophers, I have also put together some resources online.
Here is a website on the Philosophy Ph.D. application that my fellows back at Texas Tech and I put together when we just finished our Ph.D. applications and received some good news. On the website, we share our experiences of preparation (including a rough timeline of the application process), resources we found helpful, and provide some tips for potential applicants.
For people who read traditional Chinese/Taiwanese Mandarin, here is another helpful website on pursuing academic philosophy put together by a group of Taiwanese philosophers doing philosophy abroad. I have a piece (co-authored with another Ph.D. candidate in philosophy at UBC, Katherine Chieh-Ling Cheng) on experiences of doing Master in philosophy in the US.
