I signed a job contract electronically one month ago, subject to references. My two referees were approached and as far as I know they both gave good references. However, I haven't heard from my future employer yet. I sent an email to HR two days ago asking if they need anything else from me, but no answer yet.
I have already given my notice and yesterday was my last day at the old job. Start date at the new job is in 2 weeks time. Should I be worried?
