I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.\n\nAnd I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.\n\nNext steps\n\nStep 1. Visit our website.\n\nStep 2. Click 'Talk to Jack'.\n\nStep 3. Talk to Jack so he can understand your experience and ambitions.\n\nStep 4. Jack will make sure Jill (the AI agent working for the company) considers you for this role.\n\nStep 5. If Jill thinks you're a great fit and her client wants to meet you, they will make the introduction.\n\nStep 6. If not, Jack will find you excellent alternatives. All for free.\n\nWe never post fake jobs\n\nThis isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.\n\nSometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.\n\nWe appreciate this can make them look a bit suspect, but there isn't much we can do about it.\n\nGive Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.",
