Bro, to be blunt, you'll waste your time and application fee. FPSC, not only for this post, but for all posts strictly follows the recruitment rules. In this case, they not only have mentioned 2 years experience but also they have confined the experience to be of Security Agency / Law Enforcing Agency.

And even if you would clear the test, you'll receive a letter of rejection on the pretext that you lack the requisite post qualification experience.
