Resume stalking on LinkedIn can help you reverse-engineer the career you want. Here’s how to do it.

If a job seeker is not sure what companies or industries they are interested in, Ng has some recommendations on how to narrow it down. He recommends job seekers ask themselves three questions.

First: “Which words sounds cool to me?” Ng has a list of more than a thousand companies with early-career programs that can be sorted by industry, so job seekers can quickly select those that sound interesting, such as “technology,” “consulting,” or “hospitality and tourism.”

Second: “If I look around my daily life, what brands/logos do I see that seem interesting?”

Third: “What city do I want to live in?” If a job seeker knows where they want to live, they can specifically search in Google for major employers in that location.

Once a job seeker has narrowed down some companies that seem interesting, they can try out the LinkedIn stalking and take note of any patterns to narrow down their job search.

Ng said job searching is like playing the board game Battleship.

“In Battleship, you’ve got rows and columns — and the game is all about guessing which row and column the opponent is hiding a ship. In career navigation, you’ve also got rows and columns — it’s just that the rows are ‘functions’ and the columns are ‘industries,'” he explained.

Functions are specific departments at a company, like sales, marketing, HR, or product development, while industries are groups of companies that work in a specific sector.

He said the key to finding the career you want is nailing the intersection of the function you want to do and the industry you want to work in. Pouring over the resumes of people who have found what that ideal role might be for you can help you figure out what it actually takes to get there.
