400+ senior architecture and scenario questions. For each one: the answer most developers give, what the interviewer is really testing, and the answer a lead architect gives, in a structure you can say in 60 seconds.

Sound familiar?
Experienced developers say the same thing in public forums:
the knowledge is there, but the answer comes out like a developer's, not an architect's.
I have 6 yrs experience, but in interviews I go blank on scenario-based questions.
I am answering design questions like a senior developer, not an architect.
I struggle to explain why this design over the others, to senior architects or clients.
Self-study modules give theory, but don't teach real-world architectural trade-offs.

They test whether you chose, or just used the only option you knew.
"Why not a subprocess?" is where most answers fall apart.
A correct answer with no cost named still sounds junior.
See the difference
One real question from the kit. On the left, what most developers say. On the right, what gets the nod.

The method
Five steps, in the same order, for every design question. The trade-off is the step that makes you sound senior.

How each question works
You don't just read the answer. You see why the obvious answer fails, what the interviewer is listening for, and how to check your own recording.
Platform facts are checked against Pega Official websites and documentation.


What loses the room
Every question in the kit tags the red flag a weak answer shows, so you learn to hear it in your own voice.
You know which buttons to click, but not the pattern behind them.
"I'd just configure it in App Studio."
You can name the feature but not why it fits this requirement.
"We used a data page because it's best practice.
You jump to a fix without saying how you'd investigate.
"Restart the node and check again."
Said REST, but not how to handle auth, mapping, errors or retries.
"We called the REST service."
