At VIT Vellore, placements are primarily based on your performance during your degree rather than your 12th-grade marks. While some top-tier companies may have a 10th and 12th percentage criterion (usually 75% or above), most recruiters focus on the following factors:

1. CGPA: A CGPA of 8.0+ increases your chances of getting shortlisted for high-paying companies. Some companies have a CGPA cutoff (e.g., 7.5 or 8).

2. Technical Skills: Proficiency in coding (for IT roles), core subjects (for non-IT roles), and relevant tools (e.g., Python, Java, MATLAB) is crucial. Competitive programming and projects add value.

3. Internships & Projects: Companies prefer students with hands-on experience. Internships, research projects, and personal coding projects improve your profile.

4. Aptitude & Communication Skills: Most companies conduct aptitude tests covering quantitative, logical reasoning, and verbal ability. Strong communication skills are essential for interviews and group discussions.

5. Certifications & Extracurriculars: Relevant certifications (e.g., AWS, Data Science, AI, Machine Learning) boost your profile. Participation in hackathons, clubs, and leadership activities also helps.

To improve placement chances, focus on academics, build a strong skillset, do internships, and prepare well for aptitude and interviews.
