Teladoc Health is the largest telehealth platform globally — public, $2B+ in revenue. The interview emphasizes regulated healthcare engineering: HIPAA compliance, EHR integration, video consultation, and the unique scale of US telehealth.
Process
Recruiter screen → 60-minute coding phone (DSA medium) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 4–6 weeks.
What they actually ask
- Design a HIPAA-compliant telehealth video platform — interviewers probe how you keep PHI encrypted in transit and at rest, audit-log every record access, and run the media plane (WebRTC signaling, TURN servers, recording consent). Be ready to say where video streams live — or why you never persist them — and how you isolate each patient’s data by tenant.
- Design provider scheduling at scale — focus on preventing double-booking across time zones and state licensure, reflecting provider availability that changes in real time, and matching patients only to providers licensed in their state. Expect concurrency questions: slot reservation with a TTL, or optimistic locking when thousands of patients book at once.
- Design integrations with major EHRs (Epic, Cerner) — know HL7 v2 versus FHIR, how to reconcile a patient record that exists in several systems, and how to handle retries and partial failures when a downstream EHR is slow or offline. They want idempotent writes and a clear eventual-consistency story.
- Coding: medium DSA, often with regulatory/scheduling framing — expect problems dressed up as appointment slots, interval merging, or rate limiting, but the core is standard array, hash-map, and heap patterns. State the time and space complexity and walk through edge cases before you start coding.
- Behavioral: customer focus, mission-driven (healthcare access), regulatory mindset — prepare STAR stories that show careful shipping in a regulated setting: a time you flagged a compliance risk, or weighed release speed against patient safety. Tie your motivation to expanding healthcare access.

Prep priorities
- Be fluent in Java or Python (the bulk of the codebase) — pick whichever you know best, since most rounds let you choose, and be able to write clean, idiomatic code in it under time pressure without reaching for reference docs.
- Understand HIPAA, HL7 FHIR, and healthcare data standards — be able to explain what counts as PHI, the minimum-necessary principle, and how FHIR resources like Patient, Encounter, and Observation model clinical data. Treat compliance as a design constraint you raise unprompted, not an afterthought.
- Brush up on WebRTC and video consultation patterns — understand signaling, STUN/TURN, and graceful degradation on poor connections, since a dropped call during a clinical visit is a serious failure, not a minor glitch.
Frequently Asked Questions
Is Teladoc remote-friendly?
Distributed-first since 2020. Hubs in Purchase NY, Boston, Hartford. Most engineering roles fully remote within US.
How does Teladoc compare to Amwell or MDLive?
Teladoc is the largest. Amwell is the closest competitor. MDLive (Cigna) is now subsidiary. Teladoc pays mid-tier; below FAANG.
What is the engineering culture?
Mature, regulation-aware, mission-driven. Less startup-fast than tech-native; reliable. Strong work-life balance.
