I heard some Boeing guys interviewed in Jan/Feb '13 joined in Nov '13. This I believe was the last Boeing course to run.
I think some of the last Boeing interviews of 2013 took place around end of May? Hope the guys interviewed March/April get their call soon. I assume the 12 month limit relates to the actual date of job offer, not course start date.
Very positive news on new assessment dates going out. Good luck all.
