How much do LinkedIn connections help in getting hired at a company? It depends a lot on the industry, according to a recent report from LinkedIn.

The report was based on LinkedIn data from October 2014; the researchers looked at people who posted that they had been hired for a new job in the month, then analyzed their connection history up to that point to determine whether they were linked with someone at their new company at least six months prior to starting the position.

In other words, the analysis looked at which industries tend to hire people who are already part of their employees' LinkedIn networks.

Some 16% of all hires, on average, are already connected to someone at their new company on LinkedIn prior to joining, the analysis found.
