hello guys.. thanks once again for everyone's posting it always worth it and help others.. my interview was very smooth. asked some personal details and about vacations etc and then ask to wait and handed over id however it took 1 hour 30 minutes but the interview was like 30 minutes rest time was waiting.. Good luck everyone. the officer further said you will get your work permit within 3 to 4 weeks ... keep your address up to date always as IRB contacts on mail only so if any chance misses anything case will abondend etc. it was all good and smooth love the welcoming way.
