Interviewing tips
The solutions architect hiring playbook
Solutions Architect specialist or generalist - which should you hire?
The honest answer depends on the half-life of your solutions architect surface area. If you expect to keep investing in Solution design and Cloud work over the next 18-24 months, a specialist solutions architect will out-deliver a generalist on day-30 throughput and stakeholder confidence.
If your team is under ten people, or solutions architect responsibilities are spread across two or three roles already, hire a strong generalist who has shipped this work in anger at least twice. The cross-disciplinary pattern recognition will pay for itself the first time priorities collide.
On Haystack we surface both - filtered by whether the candidate self-identifies as a solutions architect specialist and verified against their last two roles. We benchmark live salary data on every offer.
What strong solutions architects actually bring
A great solutions architect is not the one with the longest CV - it is the one who has owned a hard Solution design call and changed how they work because of how it landed. Across the architecture hires we have placed in 2025-2026, the same patterns keep showing up.
- A written 30/60/90 plan in week one, anchored to Solution design delivery milestones rather than ramp-up vanity metrics.
- An opinion on what NOT to do with Cloud, backed by an example where adding it would have hurt the team.
- Solutions Architects who pair Solution design depth with cross-functional fluency - they bring product, design and data into their decisions, not just engineering.
- Active mentorship of at least one other solutions architect or adjacent role - usually a junior - within the first quarter.
Red flags when interviewing solutions architects
Every discipline has its own pattern of plausible-sounding answers that fall apart in production. For solutions architects, these are the patterns that most often correlate with a six-month regret hire on the employer side.
- Blames previous teams for failed Solution design work without explaining what they personally shipped to mitigate it.
- Cannot name a single solutions architect project where they removed scope rather than added it.
- Defines "senior solutions architect" purely by years of experience, not by the scope of decisions they own.
- Lists Solution design on the CV but cannot describe a single trade-off they hit in production - all framework, no friction.
A sample take-home for solutions architect candidates
When teams ask us how to evaluate a solutions architect beyond a CV and a chat, we recommend a 90-minute paid take-home that mirrors real work, not a trivia quiz. The brief below is one we have refined with employers hiring across architecture teams.
Give the candidate a small, intentionally imperfect artefact tied to "design customer-facing technical solutions". Their task is to add a second capability - tied to "support pre-sales and customer conversations" - while keeping existing behaviour intact. Then grade in three parts.
- Correctness: the new work satisfies the brief and at least one edge case the candidate flags themselves.
- Judgement: did they refactor, wrap or work around the existing imperfection? Any of the three is fine - we are listening for the reasoning, not the verdict.
- Communication: a short written note explaining what they would do differently with another week, what they noticed about Solution design, Cloud and Integrations, plus working exposure to Pre-sales, Stakeholder management and Technical writing, and the assumptions they made along the way.
What to expect in the first 30 days from a Haystack solutions architect hire
By week one, the new solutions architect should have shipped a small, low-risk artefact to production or a stakeholder - a docs fix, a small process change, a first review on someone else's work. The goal is to validate the loop, not to ship anything heroic.
By week two, the solutions architect is shadowing the active workstreams, attending standups in observe-mode, and asking pointed questions about why specific decisions were made. If they are not asking those questions, the hire is going to plateau.
By day 30, they own one cleanly-scoped slice of the solutions architect surface area, have published a public ramp-up doc, and are the named point of contact for stakeholders inside that slice. Every Haystack employer gets a structured onboarding template, so you are not reinventing the playbook each hire.
