If you believe titles equate some sort of seniority, like your ideas/solutions are better simply because of your title and lower titles get lower respect, then that's a giant red flag for me as in a "no hire".

A Senior at a shop building web sites and apps for small/local businesses will not have the same experience as a Senior at a company scaling into millions of transactions per minute. There should be no disrespect in either direction. The stereotypical Senior working on high volume apps/sites (knows algorithms really well, can sniff out N+1 issues in their sleep, etc.) probably couldn't cut it at a small web/app shop. They may not have the social skills to sit down with local business owners and go through a web design process and make the customer happy whilst avoiding things like "I want a pink glowing button".

Titles don't mean anything across companies. When interviewing someone I don't care what their titles were, I care about the experience they gained and if that and their personality is a match for the organization.

I agree with you but to add, OP also misses some plausible explanations:

1. The individual has an incomplete LinkedIn that is not representative of their experience.

2. The title doesn’t matter much at the company in any meaningful way beyond pay scale

I don’t disagree, but the fact we allow titles to get out of wack with reality speaks at how we don’t have very high standards in our profession compared to many others (medicine, law, other kinds of engineering)
