A free, 44-article course for freshers in India who are looking for their first tech job without campus placement. It covers the whole search: an honest assessment of where you stand, proof of work, resume and LinkedIn, finding roles early, referrals, online assessments, interview rounds, offers and negotiation, and what to do when rejections pile up. AI is used throughout as a coach and checker, never as a ghostwriter.
