Nor can you know the level of responsibility by the job title.
I read a business article the other day. The title was something like why business leaders should listen to teenagers.
When I read the article, I found that the content was not only different from the title, but that the content was far richer than the title. The article contained several terrific stories of kids who had overcome incredible challenges. Some had horrible mental or physical experiences. Others had overcome horrible social stigmas. Still others had overcome financial challenges related to the family circumstances. The amazing thing about all of these kids is that they started organizations to support other kids who suffered the same challenges. The story of each of these kids is powerful enough to be its own story.
Not one of the stories explained why business leaders should listen to teenagers.
What each story did explain is how kids turned their solution to their struggles into solutions for other kids in the same situation. Turning problems into solutions is what businesses do. They provide goods or services that fit the needs of people who needs their goods or services.
When Edison invented the lightbulb, he solved the problem of dark streets and dark homes at night through brighter safe lighting.
The same thing is true of job titles.
There are people who have the title of president who are not presidents of companies. They more are often managers of an operating division of the company. On LinkedIn, I saw the profile of a person who had the title of president of sales at a major consumer package goods company. Both Kimberly-Clark and Campbell call their head of sales “president of sales.” However, their counterparts are senior vice president. People in sales often have overstated titles to use to open doors at their clients.
