I went through the Deloitte account executive / sales interview loop for a role in their commercial practice. The job description was vague in the way consulting sales JDs always are, so let me actually tell you what they're testing.
Full disclosure: this is enterprise consulting sales, not SaaS AE. The mechanics are different. Deal cycles are long (12-24 months), the "product" is a team of humans and a methodology, and your quota is measured in contract value, not ARR. If that's not your background, the interview will feel foreign.
The loop: Recruiter screen (30 min): background, why Deloitte, how I've sold services vs. product. Pursuit leader interview (60 min): behavioral. Deals I've won, deals I've lost, how I build executive relationships. Proposal/case exercise: They sent me a brief, gave me a week, and asked me to develop a one-page proposal outline for a fictional client with a digital transformation challenge. Panel presentation (90 min): Present your proposal, take questions. Includes two senior partners. Final partner conversation (30 min): Almost a formality at this stage. Culture and fit.
What they're really evaluating: Can you get into C-suite rooms and hold the conversation? They asked specifically about how I've navigated organizations to reach the economic buyer. Do you think in multi-year relationships, not transactions? Every answer I gave about a deal win had to connect to what happened after the close. Can you collaborate internally? Consulting sales is a team sport. The pursuit team can include 10+ people. They asked a lot about how I've coordinated across stakeholders to build a proposal.
Comp: The structure is base + bonus. Senior account executive level my offer was a $175k base with an OTE around $280k at 100% attainment. The OTE is real but so is the ramp timeline: 12-18 months before you're running your own pursuits.
If you're coming from SaaS AE and haven't sold professional services before, you'll need to reframe your entire pitch. The deal you're selling isn't a feature set. It's trust and expertise over a multi-year horizon.
