Tenure isn't a good way to measure how long people stay. Median tenure (which this is reported to be) is even worse. All a median tenure of 1.1 years days is that about half the workforce was hired in the last 13 months, but it could be either due to the number of employees growing rapidly, due to people leaving the company, or some mix. We can't tell which just from these numbers. As a thought experiment, consider a company that nobody ever leaves, growing by 20% per year. They'd double in size in about 4 years, so the median tenure in steady state is also 4 years. But that doesn't mean that people only stay for 4 years; the turnover in the thought experiment is literally 0%. Also, the numbers the article (podcast?) is claiming are not supported even by their own immediate source. The reference they have for average tenure for software developers being 4.2 years doesn't actually say that. The article actually says that it's 4.2 years for all employees and that sofware developers are about 2 years. It also has such a different number for Google (2.3 years) than the number they chose to originally quote that the methodology just can't be the same. I would guess that the second source is using mean, not median.
