Job Search Services The Career Center offers a variety of job search services, including CareerMail, a letter of recommendation compiling service, a database of job listings and on-campus recruiting events, and a resume book. If you want to receive timely updates and information about opportunities and events designed specifically for graduate students and Ph.D.s, sign up for CareerMail. To do so, register or login to Callisto and on your profile select one of the two Ph.D. specific options (Ph.D.s in the Sciences/Eng or Ph.D.s in Hum/Soc Sci). You may also sign up for one or more of the industry-oriented lists (e.g., business, Environmental, or Sciences Biological & Physical). Letter Service compiles and sends out letters of recommendation files. Callisto provides online listings of part-time, full-time and temporary jobs exclusively for Cal undergraduate and graduate students. Upon graduation, Ph.D.s can maintain access by purchasing an Alumni Advantage membership. Over 500 employers annually conduct 15,000 interviews on-campus for full-time and summer positions through this web-based recruiting system. Graduate students and Ph.D. Alumni members are eligible and there is no longer a recruiting fee for this service. Resume books are a job search tool that enables you to circulate your resume to potential employers. By including your resume in one or more of 14 books, you are allowing interested employers to view your resume and contact you directly about job openings and their recruitment activities.
