You are better off applying for LP jobs with no previous knowledge, as one LP manager told me on an interview i went on after the course. He told me i'd been scammed, and he was right. They give you a bogus certification, make you take a test that doesn't actually test any of your knowledge, so it's $300 down the drain, and no job afterwards, just a stupid looking company on your resume that makes you look like an idiot.
Do yourself a huge favor and stay away from Security Retail Group.
