Question 1

Data Analyst & BI vs BI Developer - what is the actual difference?

Accepted Answer

Data Analyst & BIs focus on build and maintain trusted dashboards and metrics. BI Developers focus on build executive and self-serve dashboards. 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 analyst & bi or a bi developer?

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 analyst & bi and bi developer 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 analyst & bi interview?

Accepted Answer

Anchor the rubric on SQL, dbt, Looker. 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 bi developer interview?

Accepted Answer

Anchor the rubric on Looker, Tableau, Power BI. As with the data analyst & bi 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 analyst & bis and bi developers?

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.
