actually, a friend of mine had (his wife actually) visa interview recently. I spoke to him yesterday. A successful interview but few hickups. I just watned to share it..
basically, he has a degree in electronics enginnering(also his job title). but on the G325 he filled out, they wrote software engineer under profession. On his job letter his title was mentioned as electrical engineering. the officer asked why mismatch? (I was surprised to hear this actually, seeing how much detail they look into). Officer asked few more questions regarding that. (his work, degree etc..etc) nothing big...just be prepared at the time of interview if such things are asked. his wife was bit shaken up by this during the interview...to me, this is ridiculous..
