As a Software Engineer at KPMG, you operate at the intersection of high-level business consulting and cutting-edge technical execution. This role is not merely about writing code; it is about architecting digital solutions that solve complex, multi-faceted problems for a global portfolio of clients. You will contribute to the development of robust applications, AI-driven tools, and scalable interfaces that form the backbone of KPMG’s service offerings. The impact of your work is significant, as you are often responsible for bridging the gap between abstract client requirements and tangible, efficient software products. You will likely collaborate with cross-functional teams—ranging from data scientists to business analysts—to drive innovation in areas like cloud infrastructure, web development, and process automation. This position is ideal for engineers who thrive in a fast-paced, professional environment where technical precision must be balanced with a deep understanding of business outcomes. ##### Tip While technical mastery is expected, KPMG places a high premium on communication skills. Be prepared to explain complex technical concepts to non-technical stakeholders clearly and confidently.

When asked if you have questions, ask about the team culture, the specific challenges of their current projects, and how the team handles technical debt.
Practice Soft Skills
Remember that at KPMG, you are a consultant as much as an engineer. Your ability to explain why a solution is good for the business is just as important as the code itself.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

Walk me through the steps you would take to optimize a slow-running database query.

Find version gaps and relay lag with window functions
outbox_event holds event_id, aggregate_type, aggregate_id, aggregate_version, event_type, payload, status ('pending','published','dead'), attempts, created_at, published_at. A projection is missing rows and you must decide whether the relay skipped events or the consumer dropped them. Write three queries over the last seven days: one listing every aggregate_id whose published aggregate_version sequence has a hole, one giving per-day counts with a running total, and one returning the newest published event per aggregate. For each, say where the window function is evaluated relative to WHERE and LIMIT. PostgreSQL 16.
Approach
- Gaps: compute lead(aggregate_version) OVER (PARTITION BY aggregate_id ORDER BY aggregate_version) in a subquery, then filter next_version <> aggregate_version + 1 in the outer query. Window functions are evaluated after WHERE, GROUP BY and HAVING and before the outer ORDER BY and LIMIT, so the predicate cannot sit in the same WHERE clause and PostgreSQL 16 has no QUALIFY.
- Say what the seven-day filter does to the answer: it truncates every partition, so the first row per aggregate has no predecessor inside the window and a hole spanning the boundary is invisible. Widen the window, or join to resource.version as the authority for the true maximum.
- Running total: SELECT date_trunc('day', created_at) AS d, count() AS n, sum(count()) OVER (ORDER BY date_trunc('day', created_at) ROWS UNBOUNDED PRECEDING). An aggregate inside a window call is legal because grouping runs before windowing. The grouping key is unique per row here so ROWS and RANGE agree, but write the frame anyway — over ungrouped rows with tied timestamps the default RANGE frame pulls in every peer row and the total jumps.
- Newest per aggregate: DISTINCT ON (aggregate_id) ... ORDER BY aggregate_id, aggregate_version DESC is the cheap PostgreSQL-only form when an index matches that order; row_number() OVER (PARTITION BY aggregate_id ORDER BY aggregate_version DESC) = 1 is the portable form and needs a subquery for the same evaluation-order reason as the gap query.
Follow-up
- Relay failover redelivers events. Does a duplicate break the gap query, and how would you detect one from this table alone?
- Turn the gap check into a continuous monitor rather than a query someone runs after an incident. What does it watch?

- Say who the caller is and what they do when the call fails halfway.
