At Silicon Labs, a Software Engineer plays a pivotal role in bridging the gap between cutting-edge hardware design and seamless end-user applications. As a global leader in secure, intelligent wireless technology, the company relies heavily on its software engineering team to build the frameworks, firmware, and software stacks that power the Internet of Things (IoT). Whether you are optimizing low-power wireless protocols, developing robust microcontroller unit (MCU) drivers, or building validation test benches, your work directly impacts billions of connected devices worldwide. The complexity of the products at Silicon Labs means that software is rarely developed in a vacuum. Engineers here work at the intersection of silicon design, systems architecture, and application layer development. This role is highly strategic; a single optimization in a Bluetooth Low Energy (BLE) stack or an energy-saving state-machine implementation can significantly extend the battery life of consumer, industrial, and medical devices. To succeed in this role, you must possess a deep curiosity about how hardware and software interact. The engineering culture is highly collaborative, technically rigorous, and deeply focused on quality. If you thrive on solving complex, low-level engineering challenges and want to see your code run on physical silicon deployed globally, this position offers an incredibly rewarding and intellectually stimulating career path.

Silicon Labs Software Engineer interview: three online technical rounds
My biggest frustration was the way HR handled scheduling and communication. The follow-up felt ego-driven, and they kept pushing me to drop my application instead of giving a clear, consistent process. I learned that the second interview would take a long continuous block, around three hours with multiple hiring managers. The plan kept changing, and I was only called for the interview after a mon…

My experience started with a scheduling mess and became an uncomfortable call. I told HR in advance that I would be overseas and might have an unstable connection because I would need a VPN. The first part of the interview was choppy, although it eventually stabilized. I could not shake how the hiring manager reacted. They seemed visibly impatient and annoyed throughout, and when I asked question…

Understand the Business
Familiarize yourself with the company's core product lines, such as their EFR32 wireless Gecko platform. Knowing their target markets (smart home, industrial IoT, smart metering) will show interviewers that you are genuinely interested in their business.
Draw on the Whiteboard
During technical discussions, do not hesitate to draw block diagrams, state machines, or circuit schematics on the whiteboard. Visualizing your thoughts helps interviewers follow your logic and demonstrates structured thinking.
Writing code before the input contract is pinned down
Before the first line, state the types, the size bounds, whether duplicates, negatives or an empty input are possible, whether the input is sorted, whether you may mutate it, and what the function returns when nothing matches. Every one of those answers changes the code, and discovering one at minute twenty costs a rewrite you no longer have time for.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.

Denormalise tenant onto revisions and backfill it live
resource_revision (revision_id, resource_id, version, actor_user_id, change_kind, patch, request_id, created_at) has 400M rows and no tenant column; tenant_id lives only on resource. Two reads need it: a tenant-scoped audit feed ordered by created_at DESC, and an offboarding purge. Both join back to resource today. Justify adding tenant_id to resource_revision against those two reads, name the anomaly the copy introduces and the constraint that prevents it, then give the ordered migration for a live table taking 1.2k writes/second — the lock each step takes, how the backfill is batched, and where each step stops being reversible. PostgreSQL 16.
Approach
- Justify from the access path rather than from taste. Without the column, the audit feed either scans resource_revision by created_at and discards other tenants' rows, or resolves the tenant's resource_ids first and probes with them — both proportional to the tenant's whole history rather than to one page. With (tenant_id, created_at DESC, revision_id DESC) it is a seek that stops at 50 rows, and the purge becomes a ranged delete instead of a join.
- Name the cost exactly: a second copy of a fact can disagree with the first. Make the disagreement unwritable rather than documented — add UNIQUE (resource_id, tenant_id) on resource so it can serve as a foreign-key target, then FOREIGN KEY (resource_id, tenant_id) REFERENCES resource (resource_id, tenant_id) on the revision table. A revision can then only ever carry its parent's tenant.
- Step one, expand: ALTER TABLE resource_revision ADD COLUMN tenant_id BIGINT NULL, with no default, so it is a catalogue change and no rewrite. It still needs ACCESS EXCLUSIVE for an instant, and that instant queues behind the longest open transaction on the table while every later query queues behind it — set lock_timeout to 2s and retry rather than wait.
- Step two, dual-write: deploy the writer that populates tenant_id on every new revision while reads still use the join. Reversible by redeploying the previous build, because nothing reads the column yet.
Follow-up
- The backfill is half finished and a rollback is required. What state is the table in, and what does the previous build do with a half-populated column?
- How do you verify the backfill actually finished, given rows are still being inserted while it runs?
Stop tag and share joins from fanning out a page
resource_tag is (resource_id, tag_id) with PK (resource_id, tag_id); resource_share is (resource_id, shared_with_user_id, permission). The tagged-and-shared listing inner-joins resource to both, filters tenant_id, tag_id = ANY($2) and shared_with_user_id = $3, orders by updated_at DESC and takes 50. Pages come back with fewer than 50 distinct resources and the total in the header is far too high. Explain the row multiplication, rewrite both the page query and the count query so each is correct, and name the index each one needs. PostgreSQL 16.
Approach
- Do the arithmetic against the predicates that are actually there. An inner join emits one row per matching child row, and both joins are filtered: tag_id = ANY($2) admits only the requested tags, shared_with_user_id = $3 admits one user's share rows. So a resource holding three of the requested tags and shared with $3 once yields three rows, not one — the multiplier is its count of matching tags times its share rows for that single user, and that second factor is 1 unless the table admits duplicate (resource_id, shared_with_user_id) pairs. LIMIT 50 then limits rows rather than resources, and COUNT(*) counts pairs — the header is the product, not the population.
- Reject DISTINCT as the fix. It deduplicates after the product has been built, so the planner must materialise and sort the fanned-out set before the LIMIT can apply, and it leaves any SUM or AVG in the same select list wrong.
- Rewrite both filters as semi-joins, keeping resource as the only row source: AND EXISTS (SELECT 1 FROM resource_tag rt WHERE rt.resource_id = r.resource_id AND rt.tag_id = ANY($2)) and the same shape against resource_share. A semi-join stops at the first match per resource and preserves the driving index order, so ORDER BY updated_at DESC, resource_id DESC LIMIT 50 still stops after 50 rows.
- Count with the same predicates and no join at all: SELECT count(*) FROM resource r WHERE r.tenant_id = $1 AND r.status = 'active' AND EXISTS (...) AND EXISTS (...). Nothing multiplies a resource, so the number is the population.
Follow-up
- The filter changes from 'any of these tags' to 'all of these tags'. Rewrite it and state what it costs relative to the ANY form.
- A resource can be shared with the same user twice under different permissions. Does your count change, and should it?

How much hardware knowledge do I really need for a Software Engineer role?
It depends on the specific team, but you should expect to be tested on hardware fundamentals in almost any software interview at Silicon Labs. At a minimum, you must understand microcontroller architecture, register-level programming, and basic digital logic. Pure high-level software roles exist, but they are less common than hybrid embedded software positions.
Silicon Labs Software Engineer candidate reports ↗What is the company culture like at Silicon Labs?
The engineering culture is highly collaborative, technically deep, and relatively flat. Engineers are encouraged to ask questions, explore new technologies, and take ownership of their designs. The company places a strong emphasis on continuous learning and professional development. Some candidates have reported long delays or sudden scheduling changes during the interview process. If you experience delays, maintain professional communication with your recruiter and use the extra time to refine your technical preparation.
Silicon Labs Software Engineer candidate reports ↗How should I prepare for the coding portions of the interview?
Focus on writing clean C code on a whiteboard or shared document. Practice manipulating pointers, managing buffers, and writing state machines. Unlike traditional enterprise software companies, Silicon Labs interviewers care more about your code's memory efficiency, execution speed, and hardware interaction than complex abstract design patterns.
Silicon Labs Software Engineer candidate reports ↗Does Silicon Labs support remote or hybrid work for software engineers?
Silicon Labs generally adopts a hybrid work model, allowing for a balance of remote work and in-office collaboration. However, because many software roles require physical access to lab equipment, target boards, and silicon prototypes, regular on-site presence at their major engineering hubs (such as Austin, Boston, Singapore, or Budapest) is highly valued and often necessary.
Silicon Labs Software Engineer candidate reports ↗What topics does Silicon Labs test in interviews?
Silicon Labs interviews most often cover C Programming, Stakeholder Management, Embedded Systems, Communication Skills, and C++ Programming. The exact emphasis depends on the specific role you apply for.
