Most of it!
And the time you are not working with the data crunching numbers, you are:
- Working with the clients trying to get the cited data or validate it
- Presenting data-driven conclusions to clients or leadership
Hence, client management skills are equally important.
However, key thing is to be pretty confortable at least with Excel by the time you start, in order to survive -deadlines are super tight-.
Hope it helps!
