damn men y r u going for call centre . when u hav taken so 
much risk about ur studies den y da hell u want to join 
call centre . go n do some engineering job  . y u hav 
waisted ur parents money when u hav to join bpo.

tell them that call center also lot of electrical circuits 
and connections if any of the electrical fails i can 
implement my enggineering skill so i can do double job one 
is call center and other os electrician 
ull be the first person to get selecvted with a very gud 
pay man!!

tell them,that ur so interseted in call centers,to devlop 
ur comunication skill,n  now u feel that call center is the 
bigeset plat form for growth carrer, 
i think its work becoz i m also a elect. engg.
best of luck

truely speaking career is different frm education,there r 
so many great leaders in india who had proven this 
statement for eg:our great leader mahathma gandhi is 
basically a lawer but he proved himself as a father of our 
nation likewise if u start as an employer in a bpo u might 
gradually grow urself as a team leader,tso,etc..so never 
mind whether u r engineer or docter,the thing is u must 
prove urself at the given task so tat u can shine in this 
sector too.nothing is impossible in this world untill 
unless we try or experience ourself to it.

buddy,i think this is the toughest question of all
i understand  you should have had a bad engineering  
for this you should approach him with an air of confidence 
that what you tell him is true ,and he is beleiving it.

tell him that though u did ur engineering you were always 
inclined towards bpo sector and were planning  for it 
for some strong reasons like my brother was doing the 
same , most of my friends were working there, or you were 
not interested in the engineering sector for its mysticism, 
and have never beleived in getting a job there, 
or something like "i beleive that its quite good over 
 once i consolidate my position and then work out my way 
up  to better positions with the many opportunities in your 
company (a team leader ,etc,etc)
