for Fingerzcrossed
Fingerzcrossed - i have recently been to an OD and made it to the final interview for the 2nd time...however still waiting for (hopefully!) the GC.
I was also worried that i might be rejected at an earlier stage during the AD...but luckily i made it.. Honestly i didn't prepare myself any better for the AD! I was just myself .. no different than my first time applying. So that's what i think you should do too... That's how you made it through all rounds previously and that's how you will make it again! :-)
For the FI i prepared myself better by anticipating the questions...search the forums! Loads of possible sample qeustions, think of what they had asked you last time...moreover think of those questions (if there were any) which left you wondering for a couple of minutes before you could give a reply..and work on them!... You said you lost your English...so practice! :-)
I hope this helps, maybe someone else could give you more feedback about it....goodluck! :-)
