Can take 4-5 weeks, u never know
Just be patient, no news is good news
Im sure u gonna be alrite and they just going to move ur DOJ a bit as they did with mine.
Took me 10 weeks form my open day till actuall DOJ so sit back and relax!
They usually slow in HR and with all shifting from old to new HQ these days they might be in a bit of mess
Keep Discovering, hehe
