firstly i want to be a part of your company.......its name
is all high........ and working here my dream from very
childhood
secondly regarding salary also plays a major role...

actually what i feel is 
professonally whatever we do or does, do it for money 
and if we r getting more from the other source or job we 
wil definetly leave the current 
that is the main cause as i was not gettin as much money as 
much i work 
and ur company have ample amount of opportunity for my 
personal growth and ample amount of money that why

(First Of All do not speak anything bad about your previous 
organization cause that will creates a bad impression.)
Yous can use these points:
1.)For better Job prospects.
2.)Change of Residence.
3.)Was always interested in theis industry but never got a 
chance.
