Discovery & Qualification

3 questions

Running a discovery call, qualification frameworks, and mapping business pain to technical capability.

hardScenarioBehavioural

Your only contact is an architect who loves the product and cannot get you in front of anyone with a budget. What do you do next, and when do you stop?

Work out whether there is no project, a project owned by somebody else, or a champion nobody internally listens to, because each has a different next move. Then make one specific ask that requires other people, and treat a refusal as the qualification answer. It also connects multi threading to the point an interviewer is testing.

Take me through how you run a technical discovery call.

Set an agenda, ask about the business outcome and current process before any technology, and use the call to qualify rather than to collect requirements: establish who decides, what changed to make this the quarter they act, and what would have to be proven, then confirm it in a written recap.

hardScenarioCase Study

The customer keeps asking for one thing and everything else you hear says they need something different. What do you do with that in discovery?

Treat the contradiction as information rather than an error to correct: work out whether the stated requirement is stale, a proxy for a driver nobody will say aloud, or a political commitment, then test it against something already decided, and put both readings in writing with a price on each.

Solution Design & Proposals

3 questions

Turning requirements into a defensible solution, reference architectures, and writing the proposal narrative.

hardDesignCase Study

How do you turn discovery into a proposed architecture and a written proposal that survives procurement?

Design around the constraints the customer cannot change, offer two options and a recommendation, and write the document so a stranger can evaluate it — with an explicit assumptions register, priced exclusions, acceptance criteria and change control, because procurement turns your prose into contract schedules.

hardScenarioCase Study

How much design detail do you commit to in a proposal, knowing the architecture will change in month two and the document becomes the contract?

Detail wins evaluations and freezes decisions you have not earned the right to make yet, so split the document: commit to interfaces, outcomes and constraints, and label internal structure as indicative with an explicit route for changing it.

hardDesignCase StudyScenario

You have been handed a scope and a budget, and the budget cannot buy the scope. What do you put in front of the customer?

Show the arithmetic once, then convert the gap into a decision the customer can take: what the stated budget genuinely buys as a coherent first phase, what the full scope costs, and which specific outcome is deferred. Never deliver the full scope at the reduced number.

RFP & RFI Response

3 questions

Deconstructing an RFP, compliance matrices, win themes, and managing a bid under time pressure.

hardScenarioCase Study

The compliance matrix wants a yes or a no against a requirement you only partly meet, and there is nowhere to explain. What do you put in the box?

A bare yes is a contractual representation you cannot support and a bare no scores zero, so the answer is a qualified compliance marking with the explanation carried where the evaluators will read it. Use the clarification window before you are forced to choose.

hardScenarioCase Study

The bid is due in five days, three technical sections are unanswered and the clarification window has closed. How do you run the last five days?

Triage against the published scoring weights rather than by discomfort, freeze the solution and the price on day one, spend the remaining capacity on unanswered high-weight requirements and the compliance matrix, and reserve a full day for a red-team read and submission mechanics.

mediumScenarioCase Study

An RFP has just landed. How do you decide whether to bid on it?

Treat bid/no-bid as capital allocation: a response costs scarce senior engineering days, so qualify on stakeholder access, who authored the requirements, timeline realism and prior relationship, then bid with a real win theme, bid conditionally, or decline so the relationship survives.

Demos & POCs

3 questions

Demo storytelling, handling a live failure, and defining POC success criteria that convert.

mediumScenarioBehavioural

Mid-demo, the prospect asks whether the product does something it does not. What do you say?

Say it does not, then find out what the requirement behind the question is, because what decides the deal is whether the gap blocks them and what the honest path around it costs. A soft yes turns into a contractual obligation that somebody else has to deliver.

5 minmid, senior, staff, lead

hardScenarioCase Study

How do you scope a proof of concept so that it closes the deal?

Scope a POC around the two or three technical claims genuinely in doubt, with written pass/fail exit criteria signed off by the person who will decide, a hard time box, and named customer resources committed before any work starts.

7 minmid, senior, lead

hardScenarioCase StudyBehavioural

Your POC met every exit criterion and the customer bought from someone else. What went wrong?

A POC removes a technical objection; it does not create a buyer or a business case. Deals lost after a passing POC are usually lost on the commercial track that stood still while the technical one ran, or on criteria measuring what you are good at rather than what the buyer had to decide.

Estimation & Commercials

3 questions

Effort estimation, staffing and delivery models, licensing and TCO, and margin awareness.

hardCase StudyScenario

How do you size and price an engagement when the scope is still uncertain, and what do you do when you are told to cut the number?

Estimate bottom-up against comparable work, carry an explicit three-point range with contingency as a visible line, then choose a commercial shape that matches the uncertainty. When asked to cut, change scope, phase or team mix — never re-estimate the same work downwards.

hardCase StudyScenario

How do you turn an effort estimate into a delivery date you would defend, and what do you do when the sales lead has already promised an earlier one?

Convert effort to duration through explicit productive capacity, then check it against the critical path and the customer's dependencies, because dates are often bound by sequence rather than effort. Against a promised date, commit a smaller scope rather than a compressed plan.

5 minmid, senior, staff, lead

hardScenarioBehavioural

Who inside your own company signs off an estimate before it reaches the customer, and what do you do when the delivery lead refuses to own the number?

An estimate nobody in delivery has accepted is a number your company will be held to and nobody will defend. Get the person who will run the work to own it before submission, and when they refuse, escalate the disagreement in writing rather than averaging it away.

Objection & Competitor Handling

3 questions

Answering a hostile technical objection, competitive positioning, and conceding a real gap credibly.

hardScenarioBehavioural

In the room, the customer tells you a competitor has committed to something you cannot match. How do you respond?

Do not dispute the claim; ask what it includes. Most unmatchable claims are matchable claims with a different scope or a hidden assumption underneath them, so decompose it against your own basis, concede honestly where the competitor is genuinely better, and make sure the customer knows what question to ask them.

hardScenarioCase Study

The business wants to buy and their security team has blocked you over an answer in your questionnaire. How do you get the deal moving again?

Find out whether the blocker is a real control gap, a wording problem, or a policy that cannot bend, because only one of those is an engineering conversation. Then work with the reviewer rather than round them, and never let sales rewrite an answer to unblock it.

6 minsenior, staff, lead

mediumScenarioBehavioural

A prospect asks for a capability your product genuinely does not have. How do you respond?

Say clearly that it is not available today, find out what outcome sits behind the request, and offer the nearest credible path — never imply a roadmap commitment you cannot get in writing, because that is the objection that loses deals at renewal rather than at signature.

Presales Scenarios

3 questions

Role-play situations: a sceptical CTO, an impossible timeline, a feature you do not have, a losing bid.

mediumScenarioBehavioural

You are mid-demo and the product fails in front of the customer. What do you do, and what do you do afterwards?

Name the failure out loud immediately, take one narrated attempt at it, then route around it to keep the meeting's purpose intact. Afterwards, send a same-day written note saying what broke and what you are doing, tell the truth about whether it was a defect or a gap, and re-demo on a named date.

6 minentry, mid, senior

hardScenarioBehaviouralCase Study

You are convinced the company should walk away from a deal that everybody else wants to win. How do you make that case, and what do you do if you lose the argument?

Separate what is technically true from what you would prefer, write it as a one-page recommendation with named conditions that would change your view, and escalate to the level that can accept the risk. If overruled, get the risks recorded and stop objecting.

hardScenarioBehavioural

You are on a reference call and your existing customer starts telling the prospect the implementation was painful. What do you do, in the call and afterwards?

Let them finish, because interrupting a reference confirms the worst reading of it. Then use the call to establish what specifically went wrong, and treat the existing customer's unhappiness as the problem to fix rather than as a sales incident to contain.
