I have received a verbal offer and have verbally accepted the offer for a new position within the same company where I currently work. The written offer is contingent on a reference from my current supervisor. This just happened Friday at close of business.
Before this happened, I was already in the interview process for a different position, also within the same company (large company but same HR department). I had been given a technical problem to solve and am scheduled for the second round of interview to present the solution of the problem on Tuesday.
So...can I still go to the interview on Tuesday or is that a no-no? I have already solved the technical problem and think I did a kick ass job on it. I realize at this point I am probably bound to taking the other job, but I want to at least present the solution and go interview for networking purposes as I think I'd definitely be interested in working for or even collaborating with those folks in the future. And in the off chance that the verbal offer from this other place doesn't turn into a written offer, I want to still have another option.
But I don't want to risk upsetting the people who gave me my verbal offer and have my verbal offer rescinded if they find out that I went for this other interview after accepting the verbal offer.
One solution I thought of is to call HR Monday morning and explain the situation honestly and ask them if they think it's acceptable to go to this other interview or what do they suggest I do?
Is that a good way to go (calling HR) or is it even a bad idea to call them?
Please advise on this sticky situation.
