Question 1

Data Architect vs Solutions Architect - what is the actual difference?

Accepted Answer

Data Architects focus on design data platforms and target architectures. Solutions Architects focus on design customer-facing technical solutions. The two roles are often confused because they sit next to each other in modern delivery teams, but the day-to-day work, the success metric and the interview rubric are not the same.

Question 2

Which is easier to hire - a data architect or a solutions architect?

Accepted Answer

Both pools are active on Haystack. First shortlists land within 24 hours of kick-off for either role. Compensation varies by sector and seniority; we benchmark every offer against live UK, DE and US data.

Question 3

Can the same person cover both data architect and solutions architect work?

Accepted Answer

Often partially. Senior generalists carry one as their primary discipline and one as supporting, but expect a 60/40 split rather than 50/50 - the deep work in either role rarely happens in the same week. If the workload sustains, hiring one of each is almost always the better long-term call.

Question 4

What skills should I screen for in a data architect interview?

Accepted Answer

Anchor the rubric on Data modelling, Snowflake, BigQuery. We surface every Haystack profile with the specific tooling, levels and shipped-work examples so you can shortlist against a real skills bar, not buzzwords.

Question 5

What skills should I screen for in a solutions architect interview?

Accepted Answer

Anchor the rubric on Solution design, Cloud, Integrations. As with the data architect role, the easiest way to compare candidates is a 90-minute paid take-home that mirrors real work - never a trivia quiz.

Question 6

Do you cover senior and lead-level data architects and solutions architects?

Accepted Answer

Yes - the full ladder from junior through staff/principal in both. The kick-off call captures the level and shipped-work bar you need, and shortlists are filtered accordingly.
