2nd Time(March-2012)- I did not appeared in Interview due to unavailability.
3rd Time(September 2015)-Again refused as Training period was nine weeks and i have not provided sufficient information to VO and I did not answered properly for previous visa refusal question as i was to expecting those questions.i was bit nervous this time as well.

4th Time(October 2015)-After 3rd refusal we reapplied again after 15 days and got refusal again as VO said circumstances are not changed you need to wait and re apply later.I was confident this time and had answered each question properly.
