Zillow·Machine Learning Engineer·Onsite - Behavioral / Leadership

Jul 2026
Behavioral screen for an MLE role at Zillow. Three questions, all centered on a single recent project you pick yourself, so the pressure is on you to have a good story ready.
  • Walk me through your background and what you've been focused on lately.
  • Tell me about a recent project you owned end-to-end. What was the goal, your specific role, and what did you actually deliver?
  • What was the hardest problem you ran into on that project, and how did you work through it?

“Pretty standard opener.”

Zillow ML engineer interview focused heavily on multimodal model training and the differences between reasoning-focused versus standard chat LLMs. Conceptual depth was clearly the priority here, no coding, just talking through trade-offs.
  • When training a multimodal foundation model that handles both text and images or audio, what do you see as the biggest challenges? Pick one or two and go deep.
  • How does a reasoning-focused LLM differ from a standard instruction-tuned chat model, specifically in terms of training objectives, inference behavior like planning and tool use, and how you'd evaluate reasoning quality?

“I went with modality alignment and data imbalance, which I think was the right call, but I spent too long on the obvious stuff like representation gaps and not enough time on the messier practical issues like how paired data is scarce and noisy.”

Zillow·Machine Learning Engineer·Onsite - System Design / Architecture

Jun 2026
Zillow ML engineer interview with a meaty system design question about RAG pipelines. Just the one question but it went pretty deep into chunking strategy, which I hadn't fully prepped for.
  • You're building a RAG system with an LLM and a vector database. Walk through how you'd design the chunking strategy for documents before creating embeddings, including chunk size, overlap, use of document structure, advanced methods like semantic chunking, and how you'd evaluate and iterate on it.

“This one sprawled in a way I wasn't ready for.”

Zillow·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Zillow product interview with a classic design question that sounds simple but pulls you in a few different directions at once. Not a lot of context given about the role or outcome.
  • How would you improve the airline boarding experience?

“I went straight to the obvious stuff, zones, boarding order, overhead bin space, and then realized I was just listing complaints instead of actually structuring a product answer.”

Zillow·Software Engineer·Onsite - Behavioral / Leadership

Jun 2026
Behavioral round for a bizops role at Zillow. Just one question from what I can tell, focused on their 'Include and Empower' core value. Pretty standard culture-fit territory.
  • Describe a situation where you embraced a new or unfamiliar way of thinking.

“This is basically a culture value question dressed up as a behavioral one.”

Jun 2026
Interviewed for an MLE role at Zillow and got a coding question that was more algorithmically dense than I expected for that title. One problem, but it had enough follow-up angles to keep you busy for the whole slot.
  • Given an array of integers, find the maximum value of (min + max) across all contiguous non-empty subarrays. Aim for better than O(n^2) time.

“My first instinct was brute force, enumerate every subarray, track min and max, done.”

Zillow·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Zillow PM interview with a product strategy question framed around a competitor. Pretty standard round but the cross-company angle made it a bit more interesting to think through.
  • Define a north star metric for Airbnb.

“Spent the first minute second-guessing whether to anchor on supply, demand, or some combined engagement signal.”

May 2026
Zillow ML engineer interview with a coding round focused on agent architecture. The prompt was pseudocode only, which I appreciated, but the scope was bigger than I expected for a single session.
  • Write pseudocode for a ReAct-style agent loop that alternates between reasoning steps and tool-calling actions, including state management and basic safeguards like max steps and error handling.

“The pseudocode-only part was a relief but I still overcomplicated the state structure early on.”

Zillow·Software Engineer·Onsite - System Design / Architecture

May 2026
Zillow EM interview with a classic system design prompt. Not much to report beyond the question itself.
  • Design Zillow's core platform (property search, listings, data aggregation, etc.).

“This is a meaty one if you've never thought about real estate data at scale.”

Zillow·Product Manager·Onsite - Product Sense / Strategy

May 2026
Zillow PM interview with a product strategy question framed around a different company. Pretty standard case-style format, one question, nothing too wild.
  • You're a PM at Airbnb. What would you pick as the company's north star metric and why?

“The company-swap framing threw me a little.”
