Which computer science graduate knows coding when she/he completes 4 years ( excepting top colleges in India). Most of the CS students are not employable ( not said by me but Mr. NarayanaMurthy) and I agree to his statement. Likewise, for an admin/data analyst position in Chennai, recently, I am struggling to find good candidates who knows basics of xls ( my standard question is how will you multiply 5 * 8) and my 2nd question is have you used Dollar Functionality or F4 in xls . Believe me 95%( yes you heard it right 95%  could not pass this). This is the reality of Indian universities and students. They use Laptop ( in TN as you are aware, govt gives laptop in govt schools, hence economic status is not a hindrance) only for seeing videos and social media
