How the interviewer opens it
“Design a platform that connects patients with clinicians for remote consultations. It must handle patient intake, clinician assignment, and secure consultation records.”
The prompt is vague on purpose. The first minutes are for you. Reduce the prompt to the core features and agree on the numbers before you draw.
What to clarify first
- Service model and clinician eligibility
- Scale
- Intake and assignment
- Video
- Read:write mix
- Latency
- Consistency and availability
- Records and retention
- Privacy and durability
- Excluded features
The interviewer has the answers. In a SysRound round, Alex gives these answers, as a real interviewer does.
Scope of a strong answer
Core requirements
- Collect patient intake, current location, and consent.
- Assign an eligible clinician without concurrent assignments.
- Connect the patient and clinician for a secure video visit.
- Store and retrieve consultation records with access controls.
Usually out of scope
- Emergency care and clinical decision support
- Prescriptions, insurance, and payments
- Appointment schedules and external record systems
- Media codecs, video recordings, and large file attachments
What interviewers ask about
- Clinician assignment
- A clinician can serve only one patient at a time. Location rules, stale availability, and late responses can produce an invalid assignment.
- Visit progress and video access
- The application and video provider keep different state. Retries and connection loss must not create duplicate visits or restore access after a visit ends.
- Consultation records
- Records need strict access rules, durable writes, and a reliable change history. A stale draft must not replace a finalized note.
Common mistakes
- The design treats clinician presence as proof of license eligibility.
- The design expires offers but still accepts late responses.
- The design sends video through application servers without a bandwidth estimate.
- The design gives support staff or every clinician access to all clinical records.
- The design treats every media disconnect as a completed consultation.
- The design replaces finalized notes without an amendment history.
The bar by level
- Senior (L5/E5)
- Defines offer expiry, late acceptance, and retry behavior. Handles uncertain room creation and connection loss. Protects finalized notes and meets zone durability requirements.
- Staff (L6+/E6+)
- Defines invariants across assignment, media, and records. Explains recovery from partial failures. Justifies regional boundaries, license freshness, audit guarantees, and clinician capacity limits.
