Your question is a bit confusing, but I think you're asking about consulting life.
Not sure if you're talking about Detroit or Deloitte, but I'll proceed with the general themes.
In general, you're at the client site Mon-Thurs. Friday, you come into the office and have some of your Friday spent networking, participating in side initiatives/clubs/interest groups, doing expenses etc.
When at the client site Mon-Thurs, you only interact with your team.
If you don't have a project, you come in to the office every day of the workweek and will notice it's far quieter Mon-Thurs!
