Quiz Amazon Business Intelligence Engineer Assessment SQL Practice Questions

What the Amazon BIE assessment evaluates

Amazon’s Business Intelligence Engineer hiring process combines an online assessment with possible technical screening and interviews. The official candidate guide names a SQL Challenge, Working with SQL and Work Styles, followed by an optional survey. For India-based applicants, the exact vacancy and assessment invitation determine the applicable details. This guide explains how to practise the skills behind those sections without claiming that any exercise is an actual Amazon question.

Read the process before studying

Amazon’s BIE guide says candidates apply for a role and complete an online assessment. Depending on the role, requirements and assessment results, a candidate may be invited to one or more technical phone screenings or may move directly to the interview loop. The guide describes a technical phone screening as 60 minutes and says it includes behavioral or situational and technical questions. The interview loop is described as five 55-minute interviews. Because hiring needs and role requirements can differ, treat the candidate page and your recruiter’s communication as the source of truth for your process.

The official Amazon BIE interview guide sets out the named assessment components. Start there, then compare the guide with the actual invitation. Do not rely on online accounts that may describe another team, role level or version of an assessment.

Practise SQL as problem solving

The online assessment contains a SQL Challenge and a Working with SQL section. These names make SQL a clear priority, but the guide does not provide a complete public question bank. Build fluency by practising queries against small datasets that you understand. Before writing a query, define the question being answered, identify the relevant entities and decide how rows should be grouped. Then check joins, filters, aggregations and ordering against a hand-worked example.

A reliable SQL review includes more than syntax. Ask whether a join can duplicate records, whether a filter belongs before or after aggregation, and whether null values affect the result. When a query returns an unexpected number, inspect intermediate results rather than rewriting everything at once. Practise reading a prompt carefully and explaining why a query answers the stated question. These habits support precision in SQL tasks without suggesting that a specific database, schema or question will appear in the live assessment.

Connect queries to business meaning

Amazon describes BIE work as involving analytics, metrics, reporting and the translation of business needs into analysis. Its guide lists SQL and basic scripting, analytical problem-solving, visualization and reporting, and business acumen or requirements gathering among technical competencies. Candidates can use those areas to guide broader practice: take a simple business question, identify the metric that could answer it, state what data would be needed and explain the limits of the conclusion.

For example, when reasoning about a changing metric, distinguish a real change from a change in data coverage or definition. Ask whether the comparison uses the same time period and population. If a stakeholder’s request is ambiguous, formulate a clarifying question before selecting a calculation. The ability to explain what a number means and what it does not establish is important in analytics work and helps make technical reasoning understandable to a non-specialist.

Review workstyles and behavioral examples

The Work Styles section is part of the BIE assessment, and the guide identifies it separately from the SQL components. Answer workstyle prompts honestly and consistently. Do not try to reverse-engineer an ideal personality or choose options that conflict with how you actually work. Reflection is more useful than scripting: consider how you manage competing tasks, collaborate, learn unfamiliar tools and respond when an analysis does not support an initial assumption.

For behavioral interviews, Amazon says a significant portion of the conversation focuses on past behavior and its Leadership Principles. It recommends using the STAR method. Build a small set of genuine examples that demonstrate your individual contribution: the situation, your task, the action you took and the result. Include reflection on what you learned. Where metrics are available, describe them accurately; do not invent figures to make an example sound stronger.

Make practice measurable

Use short practice blocks with a specific objective. One session might focus on joins and aggregation; another on interpreting an existing query; another on explaining an analysis in everyday language. Keep an error log that captures the cause of a mistake, not merely the final correction. Examples include ambiguous prompt reading, an incorrect join condition, a duplicated count or a conclusion that goes beyond the data. Revisit similar problems later to see whether the underlying issue has improved.

When you practise under time constraints, first establish correctness and then work on pace. If you struggle, separate the stages: clarify the question, sketch the data relationship, write a query, validate the result and explain its meaning. This sequence is more informative than rushing through many unrelated drills. Since the public guide does not give a fixed SQL syllabus, use the specific job description to identify relevant tools and experience expectations rather than assuming all BIE roles are identical.

Prepare for the next stage

If invited to a phone screening, practise talking through technical decisions aloud. Explain assumptions, describe how you would validate a result and identify a reasonable next check. Be ready to discuss past work accurately, including limitations or lessons. For a broader interview loop, prepare to communicate both the analysis and its practical implications: what was learned, what decision it supports and what uncertainty remains.

Before the online assessment, confirm the deadline and instructions in the invitation. Amazon’s guide says the assessment must be completed within seven days of being sent and that candidates are notified within two business days after completion about whether they move forward. Those timings are the public guide’s stated process, but follow the message sent for your own application. Complete all required sections and any survey indicated, keep the confirmation, and contact the recruiting team if technical problems prevent submission.
