As a Software Engineer at Schneider Electric North America, you do not just write code; you build the digital foundation for a more sustainable, efficient, and electrified world. Schneider Electric is a global leader in energy management and industrial automation, and our software engineering teams are responsible for creating the intelligent systems that monitor, control, and optimize energy usage across critical infrastructures, smart buildings, data centers, and industrial plants. Your work directly impacts how industries reduce their carbon footprint and transition to green energy. In this role, you will contribute to high-impact software ecosystems, such as our IoT-enabled EcoStruxure platform, edge control systems, and cloud-based analytics engines. The problem space is uniquely complex, bridging the gap between physical hardware—such as power distribution units, smart meters, and microgrids—and modern software architectures. Whether you are developing low-latency embedded systems, designing robust APIs, or building intuitive cloud dashboards, your contributions will enable real-time decision-making for millions of users globally. This position requires a unique blend of core computer science fundamentals and an appreciation for physical-digital system integration. You will work in a highly collaborative, cross-functional environment alongside hardware designers, product managers, and systems engineers.

Going into the loop without having done this.
To maximize your chances of success, keep these practical, insider tips in mind as you prepare for your interviews:
Going into the loop without having done this.
Know Your Resume Inside Out – Expect your interviewers to dive deep into your past projects, internships, and academic coursework. Be ready to explain the technical decisions you made, the challenges you faced, and the ultimate impact of your work.
Going into the loop without having done this.
Do not embellish your resume. Interviewers will ask highly specific, detailed technical questions about the technologies and projects you list. If you cannot explain the inner workings of a project on your resume, it will negatively impact your evaluation.
Going into the loop without having done this.
Align with Our Core Values – Research Schneider Electric's commitment to sustainability, efficiency, and digital transformation. Be prepared to explain how your personal values align with our mission to bridge progress and sustainability for all.

Why do you want to join Schneider Electric, and how does our focus on sustainability and energy efficiency align with your personal and professional motivations?
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?
Replace offset paging on the resource feed with keyset
resource holds resource_id, tenant_id, owner_user_id, title, body_ref, version, status ('draft','active','archived','deleted'), created_at, updated_at, deleted_at, with an index on (tenant_id, status, updated_at DESC, resource_id DESC). The listing endpoint returns active resources for one tenant, newest update first, 50 per page, today with LIMIT 50 OFFSET n. Tenants reach page 400 and rows are created while they read. Write the keyset query, define what the cursor carries and how it is encoded, and say which part of the index each predicate uses. Assume PostgreSQL 16.
Approach
- Name the two failures separately. OFFSET 20000 makes the server produce and discard 20,000 rows, so page cost grows with depth rather than with page size. Independently, any write that changes how many rows sort above the offset moves the window between two fetches, and the direction decides which anomaly you get: an insert lands at the head of updated_at DESC and pushes already-returned rows down past the boundary, so they are returned a second time; a delete above the offset, or a row whose updated_at is bumped above the cursor, pulls rows up and one is never returned at all. Nothing in the response reveals either.
- Write the seek: WHERE tenant_id = $1 AND status = 'active' AND (updated_at, resource_id) < ($2, $3) ORDER BY updated_at DESC, resource_id DESC LIMIT 50. The row-value comparison is one index range rather than a disjunction, and both columns are NOT NULL, which is what makes that comparison well defined.
- Map each predicate onto the index: tenant_id and status are equality on the leading columns, (updated_at, resource_id) is the range, and the ORDER BY matches the index order so no Sort node appears and the scan stops after 50 rows. The DESC in the definition only matters for mixed directions — a plain ascending btree on the same columns is read backwards for this query.
- Put both sort columns in the cursor and nothing the client can tamper with into another tenant: base64 of (updated_at, resource_id), validated server-side, with tenant_id taken from the principal.
Follow-up
- The client asks for 'jump to page 400'. What do you offer instead, and what does the honest version cost?
- Sort order becomes user-selectable across four columns. How many indexes is that, and which would you refuse to add?

Exports duplicate a row range about once a week
Roughly once a week an export writes a file containing a duplicated range of rows. The affected job_run rows show attempt = 1, status = succeeded, one started_at, and a lease_owner naming a different host from the one whose logs show the job starting. Leases last 30 seconds and are heartbeated every 10 from inside the handler; lease_expires_at is computed on the worker and compared against the database's now(). Find the mechanism, and give a fix that holds even if you cannot fix the clocks.
Approach
- Start from the fact that eliminates the obvious answer. attempt = 1 means no retry was recorded, so this is not a re-run after failure; two workers ran the same row concurrently and the takeover path never touched the counter. lease_owner naming a host other than the one that started the job is the same statement from the other side.
- Enumerate the mechanisms that cause a premature takeover, then find the signal that separates them. Either the lease genuinely expired because the heartbeat did not fire, which is what happens when the heartbeat runs on the handler's own thread and the handler makes a long blocking call, or it only appeared expired because two clocks disagree, since lease_expires_at is written from the worker's clock and evaluated against the database's. The discriminator is the distribution: incidents clustered on the longest exports indict the heartbeat, incidents clustered on one host indict skew. Measure both, and measure each host's offset against the database directly.
- Read the reclaim query precisely. In PostgreSQL now() is transaction start time, not statement time, so a reclaimer holding a long transaction compares against an older timestamp than expected; clock_timestamp() is the statement-time function. This is worth ruling in or out before you redesign anything, because it changes which rows look expired.
- Remove the second clock rather than trying to synchronise it. Issue and extend the lease in the database, with lease_expires_at = now() + interval '30 seconds' in both the claim and the heartbeat, so exactly one clock is ever compared and worker skew stops mattering to this predicate.
Follow-up
- The displaced worker has already streamed half the file to object storage. What makes that side effect safe to repeat?
- You now count takeovers. What alert fires on that counter, and at what threshold?
