The pdf is available here. Written by Renyu (Philip) Zhang in April 2016 after receiving placement at NYU Shanghai. The discussion is tuned for students looking for placement in OM departments of business schools. The advice is not overly surprising, but rings true. One snippet:

Compared to the need and connection attributes, the communication attribute is more controllable by a PhD student. I want to emphasize again that, in order to excel on the OM job market, you have to be a great communicator to convince schools that you have the potential to become a good colleague, a good researcher, and a good teacher. You need to train yourself to become a great communicator through continuous practices, both in casual small talks and in formal seminar presentations/teaching/public speaking. To improve the communication skill in small talks, it is advised that you regularly attend some social events (including the ones during conferences) to practice talking with others. You should also learn from the great small-talkers. Your school may also offer some communication classes that you can take. Your objective should be that, after years of practices, any stranger that speaks with you would find you a delightful person to talk with. For presentation skills, I would recommend you take as many opportunities as possible to present in classes, seminars, and conferences. You can also learn some presentation skills by taking presentation classes and/or watching videos of great presentations in, e.g., YouTube or TED Talks. Your objective of the year-long presentation skill practice is that your presentation will be clear, engaging, technically solid, and broadly appealing to the audience not familiar with your work or even your area of study.
