Solution / Enterprise Architect

Trade-off defence, NFRs, modernisation sequencing, and the stakeholder and cost conversations architects are actually assessed on.

The loop, in order

  1. Architecture & Tech Leadership12 questions · 7 topicsRounds specific to senior, staff, principal, and architect titles, where the subject is judgement and organisational impact rather than code.
  2. System Design17 questions · 12 topicsOpen-ended design rounds broken into the building blocks they draw on, plus full case studies worked end to end with explicit trade-off reasoning.
  3. Backend Engineering12 questions · 7 topicsLanguage-agnostic service engineering: the protocols, boundaries, and failure handling that sit between a coding round and a full system design round.
  4. Databases & SQL13 questions · 8 topicsQuery-writing rounds and the storage-engine reasoning behind why a query is slow, for backend, data, and DBA roles alike.
  5. DevOps & Cloud13 questions · 8 topicsPlatform and infrastructure questions for DevOps, SRE, and any backend role expected to own its service in production.
  6. Behavioural & Culture Fit13 questions · 8 topicsThe round candidates most often under-prepare, treated as a skill with structure rather than small talk, including the rubric interviewers score against.
  7. HR, Screening & Offer12 questions · 6 topicsThe recruiter and HR rounds that gate the technical loop and decide your compensation, where most candidates improvise and lose money.
  8. Working in a Domain6 questions · 3 topicsDomain knowledge as a skill rather than as a subject: why it decides between two technically equal candidates, how the vocabulary gates entry, and how to acquire it deliberately instead of absorbing it over a decade.
  9. Banking & Financial Services16 questions · 11 topicsHow a bank works underneath the app: the ledger that must always balance, the rails money moves over, the identity and financial-crime controls wrapped around it, and the regulatory reporting that constrains every design decision.
  10. Healthcare & Life Sciences12 questions · 7 topicsClinical and payer systems, where the record is legally significant, interoperability is decades of overlapping standards, and interrupting a clinician has a real cost.
  11. E-commerce & Retail14 questions · 9 topicsThe path from browse to delivered and back again, where inventory is the central consistency problem and every edge case is a real order belonging to a real person.
  12. Regulation & Compliance10 questions · 5 topicsThe rules that reach into system design across every industry, and the difference between having a control, implementing it, and being able to evidence it.

hardScenarioBehaviouralCase Study

The domain expert tells you one thing and the written procedure says another. How do you work out which one the system should follow?

Treat both as evidence, not verdicts: a document records an intention on a date, an expert reports today's practice inside their own scope. Most contradictions resolve as staleness, scope or the exception path, and practice departing from a control is a finding to escalate rather than a requirement to build.
