[somia]

I am planning ot R2I in Feb 2013.. to Bangalore..

As you can imagine I have endless questions/doubts/anxiety and would like to share some on this forum...

I am basically a Mech engineer and have completed my MS here in Aus and now working from past 4yrs. I have total about 5.5yrs of experience. I have started applying for jobs through internal ref from friends and naukri/monster etc. I dont get much response at all. I try to follow-up email/phone calls and all i get is no answer/reply to emails or we will get back to you sort of answers. Thru internal ref I had a telephonic interview in Sept mid and until date there is no closure or updates from the interview although during the interview I was told I will be contacted in a couple of weeks to arrange next round.
Do you think its best to apply thru internal ref? from Aus? or after actually moving back?
What was your exp of finding a job?
