Which social media platform is specifically designed for users to showcase their resumes and connect for job opportunities?

LinkedIn is specifically designed as a professional networking platform that allows users to create and showcase their resumes, connect with potential employers, and discover job opportunities. Its features include the ability to build a detailed profile highlighting work experience, skills, and educational background, as well as networking tools that enable users to connect with industry professionals and join relevant groups. LinkedIn also provides job listings tailored to users' profiles and career interests, making it an ideal platform for job seekers looking to enhance their professional presence online.

Other social media platforms, like Twitter, Facebook, and Instagram, serve different purposes predominantly focused on social connections, content sharing, or visual media, rather than professional networking and job searching. While these platforms might have job-seeking features or groups, they lack the comprehensive job-oriented infrastructure that LinkedIn provides, making LinkedIn the most suitable choice for showcasing resumes and connecting over job opportunities.
