I am aligned with what other said in terms of "there is no typical" day. That said for MBB in US what I have experienced and observed for Consultant level is (if local):
- Mon - Thu 8am - 6.30pm at client, 8pm - 10pm from home/office
- Fri 8.30am - 5pm with 70% client work and 30% office work (expenses, training, etc)
- Weekend 1 hour catch up Sunday night to prep for the week
If you are on travel case plan to be at client at 10-11am on Monday morning and leave client on Thursday afternoon around 3pm.
Again as other said you can have more or less intense cases vs. the median one described above and varation can be pretty significant (+50% or -25% hours vs. above) with added weekend work.
