One of the things we talked about was career options. Imo, first you want to do a broad search, and then you want to dive into specific careers. I.e. a computer science student could get into software development, system administration or consulting. If development sounds most interesting, she should learn about the differences between several technical areas (frontend/backend) as well as company types (software shop/IT dep in larger corp/agency).
One of the students picked up a book on career options for computer science students and did a 30 min talk. I wasn't really happy with the book and shortening it to 30 min didn't really help, but oh well. But it definitely broadened the horizon of most students. They either didn't have any clear picture of a job, or they knew one or two types of jobs because someone in their social circle happened to have that particular job.
If I had given my student(s) your MVP, it would have most likely failed. With 3 random jobs displayed, it's not broad enough to lay out different career options. Plus, job ads, especially for software developers, teach you as much about being a software developer as a car commercial teaches you about driving a car.
To finding "a better career", I'd still recommend my students a book that tries to list most major career options, and tries to objectively name (dis-)advantages of each job. Job ads, no matter how well done, are a terrible first place to start the search.
That said, I think you've found a problem that currently isn't solved very well and I'd look forward to the next iteration of your MVP.
