Hi my name is Jessica and I am the data scientist at Hired who pulled the numbers for this report.
The way the Hired platform works is that companies must submit an initial salary offer when they start the interview process, and so all interview requests have salaries attached to them. Of course these offers can be negotiated later, but for the vast majority of our hires on the platform, the final base salary is equal to or higher than the initial offer given at the interview stage. Therefore we feel confident that this salary data is representative (if not a slight underestimate) on 2015 salaries for software engineers.
