This is good advice ! It's true that seeing other people doing stuff puts things "in the realm of the possible" (i.e. wow, I can do that)
Many of us know very little about what people in different roles actually do or how they got there. There's a good chance that you have experience that other Forum users would be interested in; so consider writing about your job! (Especially since Career Conversations Week is starting.)
Here are some existing "job profile" posts that you can explore.
(This post is somewhat redundant with Aaron's, but I hope it's a useful reminder.)
Jobs are mysterious, and it’s pretty hard to get good information about jobs that you don’t happen to know about already.
I can present my experience as evidence for this claim. When I was finishing college, I was pretty clueless about my post-college options and kind of defaulted to graduate school (which was the main thing I knew).[1] I had realized my lack of knowledge was a problem, so I asked friends for advice. Someone told me to go on LinkedIn and check people’s backgrounds — and to reach out to people and ask for meetings. I did the former and found it helpful, but it could only do so much; I still didn’t understand the day-to-day of what an “analyst” did and whether it would be a good fit. And I was too worried about wasting people’s time to reach out for calls (except in my more limited personal network, which was heavily skewed towards academic mathematicians and adjacent crowds). I still had a picture-book understanding of jobs. The thing that really helped was talking to people at conferences and informal events later — asking about their backgrounds, what they liked, etc.
The fact that jobs are mysterious to you (especially jobs that are somewhat plausible given your values, strengths, etc.) hampers your career.
You probably won’t apply to jobs you know little about, won’t know how to build relevant skills, might end up in jobs you dislike, etc. And I expect jobs that EA Forum users have are often more likely a good fit for another Forum user than a random job would be (if only because many Forum users share some values, like wanting to use their careers or resources in significant part to have a positive impact on the world), so hearing about other Forum users’ careers can be particularly helpful.
Some specific ways an “about my job” post can help:
This post is part of the September 2023 Career Conversations Week. You can see other Career Conversations Week posts here.
For pure math, which I then deferred and didn’t go to.
You might want to check the existing set of Job Profile posts for something that's very similar, but I wouldn't worry about it (except to save yourself time); jobs have changed over time, people's experiences in similar jobs are very different, and the fact that a post is coming now and from you might be relevant & useful information.
I debated for a minute if I should do this and just did it. Thanks to Lizka, because I just copied her format.
