As a Software Engineer at Shutterfly, you are at the intersection of high-scale e-commerce and creative technology. Your work directly impacts how millions of users preserve their most cherished memories, from personalized photo books to custom home décor. You will be building robust, scalable systems that handle high traffic and complex data, ensuring that the transition from a user's digital photo to a physical product is seamless, reliable, and delightful. This role requires a blend of technical precision and product-minded thinking. You will collaborate within a matrix-oriented organization, working alongside product managers and cross-functional teams to translate abstract requirements into efficient, maintainable code. Whether you are optimizing backend services, refining frontend user experiences, or architecting systems for high-volume manufacturing workflows, your contributions will be central to the company’s mission of helping people share life’s joy. ##### Tip While the interview process can vary by team, Shutterfly values candidates who demonstrate both technical depth and a genuine interest in the product. Be prepared to discuss how your code solves real-world business problems.

PracHub editorial advice for the preparation topics above.
Communicate your thought process
Never code in silence. Narrate your logic so the interviewer can follow your approach.
Be honest about your skills
If you haven't worked with a specific technology, state that, but offer to explain how you would approach learning it.
Research the product
Spend time using Shutterfly services before your interview; understanding the user perspective is a significant advantage.
Prepare your own questions
Use the end of the interview to ask meaningful questions about the team's roadmap, culture, or technical challenges.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

- Name the brute-force solution and its complexity before improving on it.
- Choose the data structure from the access pattern, not from familiarity.
- State the target complexity and say which constraint rules the naive version out.
Follow-up
- How does this change if the input no longer fits in memory?
- What is the worst case, and how likely is it on real data?

Describe the distinctions between delete and truncate in SQL.
Describe the distinctions between delete and truncate in SQL.
Approach
- Name the grain you start from and join outward from it.
- Check whether any join is one-to-many before aggregating, or the sums inflate.
- Say which index the query would use, and what makes it unusable.
- Handle the rows that do not match: that is usually the actual question.
Follow-up
- How does the query change if that join becomes one-to-many?
- What happens to this when the table is ten times larger?
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?

Approach

Approach
- Establish what changed and when, before forming any theory.
- Pick a bisection that eliminates candidates whichever way it turns out.

- How would you tell a cause from a coincidence here?
