Freshers often make critical resume mistakes that reduce their chances of selection, such as using generic resumes, focusing too much on academics, poor formatting, ignoring relevant skills, and including unnecessary or false information. To improve job prospects, candidates should customize resumes for each role, highlight practical experience like projects and internships, use proper structure, and include relevant keywords. A clear, concise, and honest resume helps create a strong first impression and increases the likelihood of getting shortlisted for interviews.
