People get fired for that.

I call bullshit. Show me three examples of people "getting fired for giving the impression of claiming they had a PhD on LinkedIn" when there's a plausible case to be made that it was an innocent mistake with at least equal blame on the reader.

I just looked at my LinkedIn profile, which I haven't updated in at least 2 or 3 years, probably more. For reasons I don't know, it lists two entries for my education.

[UNIVERSITY XYZ]
Bachelor of Arts, Computer Science, [Second Major]
[YEAR] - [YEAR + 4]

[UNIVERSITY XYZ]
Bachelor of Arts, Computer Science
[YEAR] - [YEAR + 4]

I do have two BA degrees that I earned concurrently. I really have no idea why it shows one entry with both degrees and one entry with a single degree. Did the LinkedIn database change at some point in the last 15 years? Did I really fill out the degree fields redundantly?

Damned if I know. Did I intend for it to be confusing? Certainly not, I'm sure I just filled out the forms with what I thought the program could work with and would make sense. Maybe I used some Wizard-style Q&A format that they don't use anymore. I really have no clue at all. But there it is, ready for someone to screencap and use to embarrass me if they wanted to, mocking my apparent inability to create a properly formatted LinkedIn profile.

I also note that there's nothing filled in for "description" or "activities" or anything like that. When I was young and did not have much of a resume of relevant accomplishments in my work history, I often included, on my paper resume, an honor society membership and an elected treasurer position I'd held for two semesters in a student group. These seem like details I would have added to LinkedIn, had the interface had a section for it(as it does now). But there isn't anything there. Did I remove them? Did I just never bother to add them? Or was the "activities, etc." field added to the schema after I created my profile? Certainly, the javascript-based interactive editor available now, was not the editor I used when I originally created my profile.

What I do know is that I've never directed anyone to my LinkedIn profile. I've never encouraged an employer to review it and the only interactions I've had come from former co-workers and recruiters. At this point I consider it more of a professional obligation than anything else, and log in every so often mostly to check messages and update endorsements.

I also know that I've seen work histories that look really weird, often when people work in multiple positions at the same company for years but that company also changes ownership multiple times. So you have a bizarrely fragmented presentation of a story I know to be fairly simple. Something like "was hired entry-level, switched departments, got promoted, and is now Senior Account Manager for Whatever domain" winds up looking like a career with 5 different positions on 4 different teams in 3 different companies. I consider that to be a decent indication that many people either don't spend a lot of time on their profiles, or else find the interface cumbersome enough that they're unwilling to deal with it long enough to convey a real resume-style work history.
