Hello Vijay, placement in a good company would depend on a lot many factors other than a good CGPA, i will list out a few

• Gate score
• CGPA
• Industrial Trainings
• Internships
• Extra-curricular activities
• performance in interviews, group discussion, aptitude tests etc.

If your college has good companies coming for campus recruitments it can be a lot easier to get into, but if not, there are also other ways to get employed by a good company. keep a lookout for the hiring process of your desired companies.
