This is the written guide to interviewing for senior Pega Customer Decision Hub roles. It is built around one complete CDH programme in a large regulated enterprise, from data ingestion to nine live channels, with every design decision, configuration and outcome worked through, so that whatever the panel asks next, your answer holds together.
People who have shipped real decisioning work still lose CDH interviews, and it is almost never because they did not know the answer. It is because they had forty minutes, a single attempt, and no practised way of getting what they know out of their head and into the room.
CDH makes this harder than most platforms do. The surface area is wide, the vocabulary is specific, and the interesting questions are all why questions, which are exactly the ones you never have to answer while you are configuring something.
The guide comes in five parts: how to answer, the programme itself, the platform as it was built, the channels and the operation around them, and the questions with their answers. Every part is written about the same programme, so nothing you say in one round contradicts what you said in another.
Every section is written the way a senior answer is given: the decision, the alternative that was rejected, the mechanism behind it, and the number.
These are quoted exactly as the guide asks them. Each one is the kind of question where the first sentence of your answer decides how the rest of the interview goes.
“Why not read BigQuery directly at decision time?”
Whether you can defend a data-access decision with numbers rather than instinct. A weak answer says "performance" and stops. A senior one puts figures on the call volume, the latency budget and the cost, and names where each kind of data belongs.
“Eligibility versus applicability versus suitability?”
Whether you can draw the three lines cleanly in one breath, and then explain where a regulatory rule has to sit and why. Most candidates can define the layers; far fewer can say what goes wrong when a rule lands in the wrong one.
“How does arbitration work and how did you keep it honest?”
Whether you can state the formula and then talk about the discipline around it: how the business was allowed to intervene, what stopped that intervention from quietly breaking the model, and how you would prove it had not.
“You delivered on 24.2 and we're on '26, what's the gap?”
Whether you treat a version gap as a disqualifier or as a plan. The panel is listening for what you know is unchanged, what you know is new, and what you would do about it in your first ninety days.

Because I was giving the same advice twice a week and it was not scaling: the same three corrections, to different people, about the same handful of questions.
My work has run through decision architecture, banking programmes and migrations, which means I have sat on both sides of the CDH hiring conversation more often than I ever expected to. The pattern became hard to ignore: strong practitioners were being turned down while people with a fraction of their delivery experience interviewed better.
That was not because the panel was wrong. It was because an interview measures explanation, not capability, and nobody had ever told the strong candidates that those are two different skills, or that the second one can be learned in a fortnight.
I do not think the people who get these roles are smarter than the people who do not. I have watched enough of both to be fairly sure of it.
What they have is a rehearsed way of explaining a decision. They have said the arbitration answer out loud before. They know which order to check things in when an offer is not presenting. They can describe what they personally did without shrinking it or inflating it. None of that is intelligence. It is preparation, and it is the part that almost nobody prepares.
You can assemble all of this yourself. Read the documentation, sit enough interviews, and after a few years the language arrives on its own. That is how I got it. It is just slow, and it is expensive in a way that never shows up on an invoice: the roles you did not get while you were still learning to describe the work you had already done.
This guide gives you all of that, without the years.
P.S. The guide is written to be used in the week of your interview. If your interview is only days away, read the opening sections tonight and you will walk in with a complete programme you can speak to from the first question. If it is still weeks away, you have time to work through every section, and the thirty-two answered questions are there for a final read-through on the morning itself.

Reading closes the knowledge gap, but it does not close the performance gap. For that, you have to be asked the question by someone who will push back on your answer.
If you would rather work out whether the guide fits your situation by talking it through first, that is a better use of everyone's time, and I am happy to do it.
A straight answer on whether the guide covers what you are missing, and if it does not, what would.
It is not a course at all. There are no videos to sit through and nothing to complete in order. It is a 102-page written reference built around one complete CDH programme, worked through in twenty-seven sections, with thirty-two questions answered at the end.
You read the sections that match the round you are facing, and you re-read the model answers in the week of the interview itself.
No. Certification exams test recall against a syllabus. Interviews test whether you can explain a decision, defend a design and diagnose something that is not working, usually out loud and under time pressure.
The overlap is real but only partial. If you need the certification, study the certification material.
The programme in the guide was delivered on CDH 24.2 into an environment that has since moved to Infinity 26, which is the position most candidates are in. The core that interviewers probe, taxonomy, engagement policies, arbitration, strategies, adaptive models, Interaction History and the operating model, is the same across both.
The guide shows you how to present that gap honestly: what is unchanged, what is new in the tooling above it, and how to turn the difference into a plan for your first ninety days rather than an apology.
The guide assumes you have. What it adds is one internally consistent programme to speak from, with the numbers, the trade-offs and the lessons already worked out, so the detail behind your answers never contradicts itself under follow-up questions.
The four sample questions on this page show you the level it is pitched at, and the depth a senior panel expects behind every answer.
They are the questions most often asked in CDH hiring, and every answer is worked from the programme in the guide rather than transcribed from any particular employer's process.
Nothing here is confidential to a client or an employer, and no company's interview process is reproduced.
The guide is a digital download and is non-refundable once purchased. What it covers, and four of its questions, are on this page so you can decide before you buy.
If the file is faulty, will not open, or is not what this page describes, reply to your purchase email to raise a request. I will investigate the issue and work to resolve it within five business days. If required, I may ask you for further information to help resolve your request sooner.
No. This is interview preparation only. Nothing you buy here connects you to roles, recruiters or introductions, and it never will.
That is what the CDH Mock Interview Intensive is for: live mock rounds with a working practitioner, recorded, with a written scorecard after each one.
The guide is the preparation and the intensive is the rehearsal. Most people who want both do the reading first.
If you are not sure whether the guide covers your round, your role or the topics you find hardest, tell me what you are preparing for and I will give you a straight answer, including when the guide is not the right fit for you.
What the guide covers, and four of its questions, are on this page. If it fits the interview in front of you, it is ready to download the moment you pay.
