Last night I (and I can only presume everyone else still going through the process) received a phone call from an individual who is high up in the managerial chain of UK SAR. The individual apologised for the delay and informed me that the reason was due to making sure that EVERYONE was able to attend their interviews before offers were made.
I appreciated the personal phone call, which could just have easily have been a mass email. It also highlighted to me that Bristow are sticking to their guns, which despite the frustrating wait, I'm sure most people will appreciate.
That's absolutely fine, as long as you are confident that everyone received the same phone call on Friday night. You might be less content if that turned out not to be the case.
