I recently applied for a new job. I passed the first test and they've booked me in for a face-to-face interview.
With the confirmation email they sent me a form to fill, where I should state my current and previous salaries (for the past 3 years). What concerns me is that they also want to know if I have other incomes (like stock options) and how much it is. Sounds more like a tax return than a job application.
I've been asked about my current salary before but this seems to go a bit too far. Is it common practice? Why would they need this kind of information? They said it's to better tailor their offer, but if I have other sources of income why should they care?
UPDATE: I've just received a reply from them and they say the form is completely optional.
