Even then it's still identifiable. Here are some examples: 1. Calling yourself a CTO in past jobs, even though you gave yourself that title and there are dozens of others at that company who did the same thing. Geographic CTOs, CTOs of projects, CTOs of tiny BUs that have 30 people: just GTFO. 2. Saying you're the "Head of" something. 3. Calling yourself a visionary. Let others do that. 4. Trying to appear like you have experience in every single technology and listing an alphabet soup of protocols, buzzwords, etc. 5. Calling yourself an executive when you don't have an EVP/CxO title. 6. Bragging about a board membership on some two-bit charity that only exists so nerds can claim board membership.
Some of the posts I see are just cringeworthy if you are well versed in the field or management. Also see lots of compliments that turn around and try to focus on why the person commenting is awesome not the person they are complementing.
There was this person who made a post about how she's excited to work at some company. This post got around 50k likes and the picture was a hot woman in a nice dress. I wonder how many of those like were for the actual post and not the picture.
