Win-Loss Interview Questions: The 30-Minute Structure and Question Bank
A good win-loss interview is a 30-minute conversation, not a survey: a fixed structure, the 8 questions that matter most, and a script for consent. Copy any of it below.
A win-loss interview is a 30-minute structured conversation
The questions matter less than the order they come in. Start with the trigger that started the search, work through the shortlist and the evaluation, spend real time on the competitor the buyer picked (or nearly picked), then close with pricing and what it would take to change the outcome. Thirty minutes is enough: long enough to get past the polite answer, short enough that a busy buyer will actually agree to it.

The 35-question bank, grouped by stage
Use the full bank when you have time, or the 8 must-ask questions (marked [*]) when you only have 15 minutes. The won, lost and no-decision closing questions are separated out, because that is the one stage where the right question genuinely differs by outcome.

WIN-LOSS INTERVIEW QUESTION BANK (35 questions, by stage)
[*] marks the 8 must-ask questions if time is short
TRIGGER AND NEED

Who else did you seriously consider, and why those?
Was there a vendor you expected to consider but ruled out early? Why?
EVALUATION
[*] How did you compare the vendors on your shortlist?
What mattered most in the evaluation: product, price, trust, support, something else?
Was there a demo, trial or proof of concept? What happened in it?
Did anyone outside the buying team weigh in, and what did they say?
THE COMPETITOR
[*] Which alternative did you take most seriously, and what did it do well?
Where did that vendor feel stronger than us?
Where did that vendor feel weaker than us?
Was there a specific feature, integration or claim that stood out?
PRICING AND COMMERCIALS
[*] How did price factor in: was it the reason, or the tiebreaker?
How did our pricing compare with what you were quoted elsewhere?
Was there a commercial term (contract length, seats, support tier) that mattered?
THE DECISION
[*] What was the moment you started leaning toward (or away from) us?
[*] What almost made you choose differently?
Was there anything in our sales process that helped or hurt?
If you could change one thing about how we showed up, what would it be?
ONBOARDING / WHAT WOULD CHANGE THEIR MIND
[*] (Won) What made the first weeks feel like the right choice, or not?
(Lost) What would need to be different for you to reconsider us next time?
(No-decision) What would need to happen for this to become urgent again?
WON DEALS ONLY
What nearly stopped you from signing?
Would you be willing to be a reference or give a quote later?
LOST DEALS ONLY
Would you be willing to tell me what the winning vendor said that landed?
Is there anything we could do now that would still be useful to you?
NO-DECISION DEALS ONLY
Is this still a live problem for you, or has it dropped in priority?
What would make this active again?

The invitation email
The hardest part of win-loss is not the questions, it is getting the buyer on the call at all. The invitation has to make clear, immediately, that this is not a sales call and there is no follow-up pitch coming. Send this from the vendor directly, or from a third-party interviewer, with the two bracketed lines swapped accordingly.

SUBJECT: 20 minutes on your recent decision? (no sales pitch)
Hi [First name],
I am reaching out because [Company] recently went through a buying process
that touched us, and I would like to understand it better, honestly.
This is not a sales call. I am not trying to win you back or sell you
anything. I just want to hear what actually happened: what mattered, what
almost changed your mind, and where we helped or got in the way.
It takes about 20 to 30 minutes. With your OK I would like to record it so
I capture things accurately, and I am happy to keep anything you say
anonymous in how we use it.
Would [date/time option] or [date/time option] work? If neither does, tell
me a time that is easier and I will fit around it.
Thank you either way for the time you already gave us during the process.
[Name]
[Role, Company]
(or, if sent by a third-party interviewer): [Name], independent interviewer
working with [Company] on win-loss research
The recording-consent script
Ask for consent explicitly, at the start of the call, before anything substantive is discussed. A plain ask, with a reason attached and an anonymity offer, gets far more yeses than silently hitting record and hoping no one objects.

RECORDING-CONSENT SCRIPT (read at the start of the call)
Before we start: is it OK if I record this call? It is only so I can
capture what you say accurately rather than relying on my notes, and the
recording stays internal.
You can ask me to stop recording at any point, and you can ask for
anything you say to be kept off the record or anonymised when we use it.
This is not a sales call, there is no follow-up pitch, and nothing you say
here affects any commercial relationship between us.
[Wait for a clear yes before recording. If no, take notes only and say so.]
Questions not to ask, and why
A few question styles reliably wreck a win-loss interview by turning it into a negotiation or a performance review. Avoid them:
"Would you switch to us if we dropped the price?" It turns an honest interview into a negotiation, and buyers stop answering candidly once they think the call is a sales motion.
"Don’t you think our product is actually better?" A leading question. It invites agreement rather than the buyer’s real view, and the whole point of the interview is to hear what they actually think.
Any question that asks them to justify picking a competitor It puts the buyer on the defensive. Ask what the competitor did well instead of implying the decision needs defending.
"On a scale of 1 to 10, how happy are you with us?" A scored survey question kills the conversational tone that gets buyers to open up, and a number without the story behind it is not actionable.
Anything that reveals confidential details about another prospect or deal Breaks confidentiality and will travel back to the market faster than any benefit the question is worth.
Common questions
What questions should I ask in a win-loss interview?
Open, conversational questions grouped by stage: the trigger that started the search, how the shortlist was built, how the buyer evaluated vendors, what the chosen competitor did well, where price fit in the decision, and what would change their mind now. The 8 must-ask questions above cover each stage if time is short.
How long should a win-loss interview be?
Thirty minutes is the right default. It is long enough to get past the polite answer and short enough that a busy buyer will actually agree to it. The structure above allocates roughly 5 minutes each to trigger, shortlist, the competitor, and pricing, with short open and close segments.
Should the questions differ for won, lost and no-decision deals?
The core question bank is the same, because most of the value is in the trigger, shortlist and evaluation stages that every deal goes through. The closing segment should differ: ask won buyers what nearly stopped them signing, ask lost buyers what the winning vendor said that landed, and ask no-decision buyers whether the problem is still live.
Do I need a recording-consent script?
Yes. Ask explicitly before recording, explain why (accuracy, not evaluation), and offer anonymisation. Buyers who are asked plainly are far more likely to agree, and a clear yes avoids any question later about whether the recording was proper.
Who should send the interview invitation?
Either the vendor or a neutral third party works, but the wording should make clear this is not a sales call. A third-party interviewer tends to get more candid answers, especially on losses, because the buyer is not worried about being diplomatic with the rep who lost the deal.
