Commure had me do a coding screen that was basically a data pipeline problem disguised as a CSV parsing exercise. More design-heavy than I expected for what felt like a mid-level screen.

You're given three CSV files representing providers, patients, and appointments. Parse them line by line, validate each row, and join them into a single output where each appointment record embeds the relevant patient and provider info. Invalid rows or references to nonexistent IDs should be logged and skipped without crashing.

“The join logic itself wasn't hard but I got tripped up on the structure they wanted.”

Commure SWE interview threw a combined LRU cache plus TTL problem at me, which felt like two problems duct-taped together. The follow-up extensions they hinted at made it clear they wanted to see how far you could take the design, not just get a working solution.

Design and implement an LRU cache where each entry has its own TTL. The get operation should return -1 and remove expired entries, and put should evict the least-recently-used entry when at capacity, preferring expired entries first.

“I knew the vanilla LRU implementation cold, OrderedDict plus a size cap, but the TTL layer threw me off more than I expected.”

System design round at Commure for a frontend engineer role, which honestly skewed way more backend than I expected. The whole question was about booking flows and payment state, not a single thing about UI architecture.

Design a patient appointment booking system where users can browse provider timeslots, select one, and pay through a third-party payment processor. Cover the data model for timeslots, concurrency control to prevent double-booking, payment integration including webhooks and idempotency, the full booking lifecycle, and how you'd handle failures and reconciliation between booking and payment state.

“This is a lot to cover in one question and I didn't pace myself well.”

Commure frontend interview had a coding portion that leaned heavier on type system design than I expected. The question built on itself in a way that felt more like a backend or SDK design problem than anything UI-related.

Extend a function that filters simulation objects to support multiple conditions at once, returning only the objects that satisfy all of them. Each condition compares a single field (like age, type, or salary). How would you design a type-safe, scalable representation for this?

“This tripped me up more than it should have.”

Did a system design style frontend round at Commure for a Frontend Engineer role. The whole thing was an open discussion about handling large datasets in the UI, which sounds straightforward but there's a lot of surface area to cover if you're not prepared.

How would you optimize a UI that needs to render tens of thousands of rows or items? Walk through the techniques you'd use and the trade-offs involved.

“This was the whole conversation basically.”

System design round at Commure for a software engineering role. The whole session was basically one big rate limiter question that kept branching into more and more sub-topics. More thorough than I expected.

Design a rate limiter that controls how many requests a client can make within a given time window.

“This started simple enough but kept expanding.”

Commure SWE interview that went deep on a single design problem. The whole session was basically one extended question about caching with a twist, and they kept pushing on edge cases I hadn't fully thought through.

Design and implement an LRU cache that also supports per-key TTL expiration. It should handle get(key), put(key, value, ttl), skip returning expired entries, and evict least-recently-used when at capacity. Walk through your data structures and complexity.

“Started with the standard hashmap plus doubly linked list setup and felt pretty good about it, then they asked how expiry interacts with eviction order and I stumbled.”

Got a TypeScript coding question for a Frontend Engineer role at Commure. Pretty focused on type safety and generics, which I wasn't fully warmed up for.

In TypeScript, write a function that takes a list of Sim objects and a condition object, then returns only the Sims that satisfy that condition. Each Sim has fields like age, occult type, and salary. The condition represents a single comparison on one field. How would you type this in a clean, type-safe way?

“My first instinct was to just pass a callback predicate and call it a day, but I could tell they wanted something more structured.”
