This depends on how clear you are on your goals going in. We work face-to-face, plus email back-and-forth. I also do quite a bit of background research before we meet, based on the preliminary information I receive from you.
We usually work over 2-3 sessions, which means it takes about 2-3 weeks from our first session. That said, sometimes clients find it easier to do more shorter sessions (like 2 hours long, instead of 3-4 hours). If we need to break it up into 4-5 sessions, that works too. My priority is to make sure your professional narrative is crafted in a compelling way, and your profile gets done. Period.
