Oscar Health·Software Engineer·Onsite - Coding / Algorithms

Jun 2026

Onsite coding round at Oscar Health for a software engineer role. One problem, pretty domain-specific for a health insurance company, involved geospatial filtering and set coverage logic together.

Given a list of healthcare providers (each with an ID, specialty, and location) and a list of members (each with an ID, location, and a set of required specialties), plus a max distance value, return the IDs of members who cannot find all their required specialties from providers within that distance.

“Two things happening at once here: distance filtering and then checking specialty coverage.”

Oscar Health·Software Engineer·Technical Phone Screen

Jun 2026

Oscar Health coding screen, looked like a backend or data engineering role based on the problem. One meaty algorithmic question with a follow-up design discussion. Pretty focused session, no fluff.

Given a list of healthcare providers (each with a location and specialty) and a list of members (each with a location and a set of required specialties), find all members who do not have adequate network coverage. A member has adequate coverage if, for every required specialty, there exists at least one provider of that specialty within the member's maximum travel distance. Return the IDs of members who fail this check.

“My first instinct was to brute-force it: for each member, for each required specialty, scan every provider.”

Oscar Health·Software Engineer·Onsite - System Design / Architecture

Jun 2026

Onsite system design round at Oscar Health for a software engineer role. The problem itself wasn't particularly brutal, but the interviewer gave zero feedback throughout, which made it genuinely hard to tell if I was on track or completely off base.

Design a web-based queue management system for licensed physicians to handle telehealth consultation requests, where a physician can only be matched with patients from states they hold a license in.

“The core constraint is the state licensing restriction, and I spent a decent chunk of time on how to model that cleanly.”

Oscar Health·Software Engineer·Technical Phone Screen

May 2026

Phone screen for a software engineer role at Oscar Health. Two coding questions, both string manipulation flavored, and the second one had a follow-up that turned the whole thing into a mini word-break problem.

You're given a mapping of characters to Morse code. Write a function that converts an input string of lowercase English letters into its Morse code representation.
Given a Morse code string (no delimiters), generate all possible original strings that could have produced it.

“Pretty straightforward, just iterate through the string and concatenate the codes.”
