Wodify Cross-Platform Mobile Developer interview questions

I was contacted by an Wodify employee at LinkedIn, who invited me to a phone interview, we had a pretty friendly and pleasant talk. We talked about my background, specific skills for the job, expectations, etc... Then I was asked to formalize my application through their website, and fill an application form in a third party website, the form was completely unappropriated for such early stage, requesting every single detail of my carrear and academic history, including details about my current and previous salaries, managers name, etc. Since some of these information are company CONFIDENTIAL, I wrote them back exposing the situation, to which they answer me "shut up and fill the form" in a polite way, not having in consideration that could put me in LEGAL troubles with my current and previous employers. Obviously I didn't provided them the information which was company confidential, and we ended there the recruitment process.
