Last Wednesday I had a second interview (in person) for a position. It followed a telephone interview a week earlier and went really well.

When I inquired about the timeline for a decision I was told that they would know by the end of this week as they want the position to start during the week of the 8th.

I sent thank you notes (by mail) to both managers who interviewed me on Friday and haven't yet received word back.

I would think they would have told me earlier than Thursday or Friday of the week before if they expected me to start next week. I also realise that one or both managers could have taken a few days off for labor day.

Is it too soon to worry and should I call tomorrow?
