Depends on the role. But salespeople are there to sell stuff, the efficiency gains are orthogonal to the objective. Their job is to call people, go shake hands, get ink on dotted lines, etc. Not faff about with Excel.
Note: They also sell themselves to their bosses too. Hence why they tend to outlast engineers in largish orgs.
