The most memorable lecture in the 1-unit seminar “ENG98 Strategies for Securing an Engineering Job” at UC Davis during Winter 2019 was the one about finding a job. The speaker, brought up the importance of followups, so based on his advice I build a Gmail App Script that would do follow ups for me.
I write the first email to a cold lead, and the google script does all the work for me. It follows up weekly with a randomized human-sounding response and appends it to the email thread. That way, after a thread of 22 followups, maybe someone replies. The goal is to get a yes or a no for informational interview. No response means keep following up.
