Various companies come to colleges to hire bright students.The selection procedure generally includes an Aptitude Test followed by Group discussion and Personal interview.The selection also depends on work experience,therefore it is advisable that you should do internships during your graduation. The more you do the more stronger your CV becomes and you get.There are several private companies that look for Science graduates for technical work. Several coaching institutions also hire students who have the skills to teach.You may get the job of content writing if you have good writing skills.
