How long before....?

National Grid
#1

I have applied for engineer training programme with national grid and have received an email saying i have passed the situational judgement questionnaire and that my application is under further consideration and that they will be in contact in due course. This was two full weeks ago and i still havent heard anything more about the phone interview? Does this mean i have been unsuccessful or does ‘we will be in contact in due course’ mean they would still contact me even if i was unsuccessful? How long have others had to wait as I really hope this is successful for me as i think i prefer the idea of going to national grid over uni.

cheers
