What is a transferable skill?
Time management. I needed it when balancing a handful of demanding courses, a capstone paper I really wanted to hit out of the park, part time work, bills, (at times) a social life and rest. I need it just as much in my current role as Customer Support and Operations Manager at Addgene. In this role, I balance my daily tasks, meet cross-team project commitments, respond to any issues raised by team members, and plan for the future of the team. All while still paying bills and having a life outside my job.
The same can be said about teamwork, communication, writing, management, and creativity; I have developed these skills through school, jobs, and volunteer work, and I guarantee you have developed them through similar experiences in graduate school. These skills will be useful anywhere I work in the future; they are transferrable across most, if not all, industries and work environments. This is why they are called transferable skills.
