I have watched strong McKinsey-trained candidates lose a Willis Towers Watson interview in the first ten minutes. They treated a benefits or risk prompt like a strategy case, optimized the CFO's P&L, and never named the people whose money or coverage sat on the other side of the table.
The thesis is simple: WTW interviews reward fiduciary judgment under constraint, not a clean "grow or cut" story. The interviewer is listening for whether you can hold a commercial recommendation and a duty to participants, insureds, or regulators in the same breath — and still do arithmetic that survives a second look. After this piece you should know what WTW actually sells, what the firm publishes about its process, how a health-and-benefits tradeoff is scored, and what to practice this week.
Two businesses, not one "consulting" brand
WTW is an advisory, broking, and solutions firm. Its own early-career materials describe over 49,000 colleagues in over 140 countries. For the year ended December 31, 2025, WTW reported revenue of $9.71 billion (organic growth 5%; reported revenue down 2% after the TRANZACT sale).
The firm reports two segments. In 2025, Health, Wealth & Career posted about $5.25 billion of segment revenue and Risk & Broking about $4.33 billion — roughly a 55/45 split of segment revenue. That mix matters for your interview more than any prep-site taxonomy:
| Segment | What the work sounds like in a case | What "good" sounds like |
|---|---|---|
| Health, Wealth & Career | Plan design, stop-loss, retirement risk, rewards, talent analytics | Tradeoffs among CFO, CHRO, and participants; numbers plus process |
| Risk & Broking | Placement, limits, deductibles, captives, client servicing | Coverage language, market appetite, client vs insurer incentives |
If your invitation says Corporate Risk & Broking, do not open with a MECE market-entry tree. If it says Health & Benefits or Retirement, do not treat employees as a cost center you can "divest." Confirm the line of business on the email. The vocabulary changes; the scoring logic does not.
What WTW publishes about the process
WTW's own careers guidance is careful: process varies by role and location. For experienced hires, the firm describes a recruiter conversation, optional HireVue preliminary questions, an optional role-based assessment (skills test, business case, or work samples), a hiring-manager interview, and a team or stakeholder round.
Early-career UK programmes publish a similar skeleton with more assessment-centre weight. A 2027 Corporate Risk & Broking graduate programme in London, for example, lists: online application, online test and video interview, a virtual session on teams and skills, a virtual assessment centre, then offer. Actuarial tracks often add a face-to-face interview after the centre. Treat those stages as published templates, not a universal global script.
What is folklore versus firm fact: Glassdoor and campus chatter claim exact HireVue question counts and game batteries. WTW confirms HireVue may be used; it does not publish a fixed question bank on the candidate-journey page. Prepare for a scored video round if invited. Do not memorize someone else's leaked prompt list as if it were official.
What the interviewer is actually scoring
In a Big Four strategy room I score structure, math, insight, and presence. At WTW-adjacent work — and when I was on the other side of benefits and risk conversations with clients — the sheet tilts differently. My estimate for a typical case-style discussion:
| Dimension | Rough weight (Ned's estimate) | Fail mode |
|---|---|---|
| Clarifying the decision and stakeholders | 20% | Jumping to a framework before naming CFO vs CHRO vs participants |
| Structure that fits the product (benefits, risk, rewards) | 20% | Forcing 3C / profitability onto a fiduciary problem |
| Math that isolates the real driver | 25% | Pretty arithmetic on the wrong base (premiums only, no volatility) |
| Fiduciary or fairness check | 20% | Optimizing EBITDA while ignoring selection, communication, or process |
| Crisp recommendation with a next analytic step | 15% | Hand-waving "run the numbers" without saying which numbers |
You are not expected to invent a discount rate, quote an insurer's unpublished pricing, or claim you have passed actuarial exams you have not. You are expected to say what you would ask an actuary or broker for, and why that ask changes the decision.
Worked example: raise the stop-loss, or redesign the plan?
Prompt. CedarPath Logistics is a fictional U.S. mid-market shipper with 4,800 employees on a self-insured medical plan. Specific stop-loss attaches at $150,000 per claimant. The CFO wants to raise attachment to $250,000. The broker quotes a $1.9 million cut in annual stop-loss premium. The CHRO worries about cash spikes and about a parallel proposal to raise the in-network deductible from $1,500 to $3,000 for employees. You have 25 minutes. What do you recommend?
Clarify. Success is not "cut benefits cost." Success is a package the committee can defend: expected cost, downside cash risk, and employee impact. You may split the two levers. You are not giving legal advice; you are showing you know a benefits committee hears both finance and HR.
Structure (health financing, not market entry).
- Expected cost: premium savings versus retained claim dollars between $150k and $250k
- Volatility: how many claimants typically cross $150k, and what a bad year looks like
- Employee design: deductible change is a different product decision than stop-loss
- Operations: open enrollment timing, communications, vendor disruption
- Governance: who owns the recommendation (CHRO vs CFO vs committee)
Math you can reproduce. Suppose last year CedarPath had 18 claimants above $150k. Of those, 11 also exceeded $250k. Average dollars between $150k and $250k on the seven who stopped short: $62,000. On the eleven who went past $250k, the band between attachments is a flat $100,000 each.
Expected retained claims if attachment moves to $250k (using last year as a rough base):
- 7 × $62,000 = $434,000
- 11 × $100,000 = $1,100,000
- Total ≈ $1.53 million
Premium savings: $1.9 million. On this single-year snapshot, the expected economics look about $370,000 better. That is not yet a yes.
Now stress it. In a bad year, say 28 claimants breach $150k and 20 breach $250k, with the same band averages. Retained band cost ≈ 8 × $62k + 20 × $100k = $2.50 million. Premium savings still $1.9 million. You are $600,000 underwater on expectation versus the soft year — before you talk about cash timing inside the year.
Separately, the deductible hike is not free money for the stop-loss decision. If 4,800 employees take family coverage at an illustrative 40% rate (1,920 families) and half of those families hit the higher deductible fully, incremental employee cost is on the order of 960 × $1,500 = $1.44 million shifted to households. That number belongs in the CHRO conversation; it does not "pay for" the CFO's stop-loss move in any clean way.
Recommendation. Raise attachment only if the committee accepts roughly $0.5–0.6 million of adverse-year drag versus the soft year, funds a cash reserve or working-capital buffer for intra-year spikes, and commissions an actuary's multi-year loss pick — not a one-year anecdote. Park the deductible change as a separate total-rewards decision with employee communication and equity analysis. Do not bundle them to make the CFO slide look prettier.
A strategy-trained candidate often says "take the $1.9 million" and never builds the retained band. That is the leak.
Ned's rule. If your recommendation improves the sponsor's P&L but you cannot say, in one sentence, who bears the new risk and how you sized it, you are not ready for a WTW-style case.
Line-of-business vocabulary worth twenty minutes
You do not need an FSA. You do need to sound like you have read a benefits or placement memo once.
| If the invite is… | Learn enough to define… | Avoid sounding like… |
|---|---|---|
| Health & Benefits | Self-insured vs fully insured, stop-loss, HDHP vs PPO, vendor RFP | "Cut the cost center" with no plan design |
| Retirement | DB vs DC, lump sum vs annuity, PBGC as a cost line (not the whole case) | Treating a pension as a business unit you can sell with a press release |
| Risk & Broking | Limit, deductible, retention, soft vs hard market, broker vs underwriter | Pure M&A synergy math with no coverage |
| Work & Rewards | Total rewards, pay equity, incentive design | Vague "culture" without a metric |
On pensions specifically, flat-rate PBGC premiums are public: for plan years beginning in 2026, the single-employer flat-rate premium is $111 per participant (up from $106 in 2025). That figure is useful as a sense-check when a case waves at "premium savings." It is rarely enough, alone, to justify a messy window or a rushed de-risking.
Fit answers that do not sound like a brochure
Weak: "I like helping people with their benefits." Stronger: a short story where you weighed risk pooling, incentives, or a coverage tradeoff and can name a metric — cycle time on a reconciliation, error rate on a census file, loss ratio movement, not a personality adjective.
Why WTW versus MBB or an insurer: say you want client-facing problem solving inside people, risk, and capital — the firm's published framing — not generalist strategy staffing. Do not invent proprietary knowledge of WTW's confidential scorecards. CoachNed is independent and not affiliated with WTW or any firm named here for interview practice.
Practice this today
Take the CedarPath prompt and write a one-page stakeholder map: CFO, CHRO, benefits committee, broker, stop-loss carrier, employees. Force yourself to state the conflict in one line before you touch structure. Then run the retained-band math cold, without a calculator if you can.
For timed structure and synthesis reps, start with the five-minute case at /start (three typed turns, instant scores, no account required), or a live voice case at /interview. Drill pure arithmetic on /drills/math until the stop-loss band feels automatic. Everything on CoachNed is open for seven days with no card; then $120 for a recruiting season or $49 a month.
Frequently asked questions
Does WTW use case interviews like McKinsey?
Sometimes you get a business case or work sample; sometimes the heavy lift is HireVue plus a technical or competency discussion. WTW's candidate journey lists a role-based assessment as optional. Bring a structure anyway, but expect benefits, risk, or rewards vocabulary rather than a classic interviewer-led market-sizing marathon.
Do I need to be an actuary to interview at WTW?
No for many advisory, broking, and client-service roles. Actuarial programmes care about exam progress; do not bluff it. For Health & Benefits or Risk & Broking graduate paths, analytical comfort and clear communication matter more than an ASA on day one.
What is the WTW HireVue like?
The firm says preliminary HireVue questions may be required. Exact question counts and game formats vary by requisition and are not fully standardized on the public journey page. Treat any video round as scored: camera, tight STAR, one metric per story, no reading from notes.
How should I prepare for a Corporate Risk & Broking interview?
Read the published programme or role description for your geography. Practice explaining a limit, a deductible, and why a client might retain more risk when premium is high. Client-facing clarity beats a fancy strategy framework.
Is this guide official WTW material?
No. Confirm format, line of business, location, and compensation with recruiting. Processes change by team and year.
