Confirm the actual process
Ask for the stages, purpose, exercise rules, allowed tools and timing before planning around them.
Step 1 of 2
Do not borrow another role's process
An engineering interview note does not prove that Solutions Architect candidates complete the same rounds. Demo, discovery, build and panel exercises are useful practice only when labeled as assumptions.
Ask for the actual process
"Could you walk me through the remaining stages and what each one is meant to assess? Is there a written, live or technical exercise? I would also like to know the time limit and which tools are allowed."
Once you have the answer, replace assumptions with the recruiter's details. Keep the role posting as the source for what good performance looks like, and use the confirmed format only to decide how you will show that evidence.
