As a Software Engineer at WebMD Medscape, you play a vital role in building and maintaining the digital infrastructure that delivers critical health information to millions of professionals and patients worldwide. Your work directly impacts the accessibility and reliability of health data, supporting a platform that is synonymous with medical authority. Whether you are working on high-traffic web applications, complex data pipelines, or internal systems, your contributions ensure that users receive accurate, timely, and secure information. This role offers a unique intersection of high-scale engineering and mission-driven work. You will likely engage with a diverse stack, ranging from modern cloud-native architectures to legacy systems that require careful modernization. The environment is fast-paced and demands a balance of technical rigor and pragmatic problem-solving. Success in this position requires not only deep expertise in your primary language—often involving C#,.NET, or Java environments—but also a commitment to clean, scalable code and a collaborative mindset within cross-functional product teams.

Communicate your process
Never solve a problem in silence. Talk through your assumptions, trade-offs, and potential edge cases as you work.
Prepare for the flowchart
Practice drawing logical, clean diagrams for common system components.
Be ready for the basics
Do not overlook fundamentals like OOP concepts or basic SQL queries; these are often the "easy" questions that you are expected to nail.

What are the practical differences between Union and Union All in SQL?
What are the practical differences between Union and Union All in SQL?
Approach
- Name the grain you start from and join outward from it.
- Check whether any join is one-to-many before aggregating, or the sums inflate.
- Say which index the query would use, and what makes it unusable.
- Handle the rows that do not match: that is usually the actual question.
Follow-up
- How does the query change if that join becomes one-to-many?
- What happens to this when the table is ten times larger?
Denormalise tenant onto revisions and backfill it live
resource_revision (revision_id, resource_id, version, actor_user_id, change_kind, patch, request_id, created_at) has 400M rows and no tenant column; tenant_id lives only on resource. Two reads need it: a tenant-scoped audit feed ordered by created_at DESC, and an offboarding purge. Both join back to resource today. Justify adding tenant_id to resource_revision against those two reads, name the anomaly the copy introduces and the constraint that prevents it, then give the ordered migration for a live table taking 1.2k writes/second — the lock each step takes, how the backfill is batched, and where each step stops being reversible. PostgreSQL 16.
Approach
- Justify from the access path rather than from taste. Without the column, the audit feed either scans resource_revision by created_at and discards other tenants' rows, or resolves the tenant's resource_ids first and probes with them — both proportional to the tenant's whole history rather than to one page. With (tenant_id, created_at DESC, revision_id DESC) it is a seek that stops at 50 rows, and the purge becomes a ranged delete instead of a join.
- Name the cost exactly: a second copy of a fact can disagree with the first. Make the disagreement unwritable rather than documented — add UNIQUE (resource_id, tenant_id) on resource so it can serve as a foreign-key target, then FOREIGN KEY (resource_id, tenant_id) REFERENCES resource (resource_id, tenant_id) on the revision table. A revision can then only ever carry its parent's tenant.
- Step one, expand: ALTER TABLE resource_revision ADD COLUMN tenant_id BIGINT NULL, with no default, so it is a catalogue change and no rewrite. It still needs ACCESS EXCLUSIVE for an instant, and that instant queues behind the longest open transaction on the table while every later query queues behind it — set lock_timeout to 2s and retry rather than wait.
- Step two, dual-write: deploy the writer that populates tenant_id on every new revision while reads still use the join. Reversible by redeploying the previous build, because nothing reads the column yet.
Follow-up
- The backfill is half finished and a rollback is required. What state is the table in, and what does the previous build do with a half-populated column?
- How do you verify the backfill actually finished, given rows are still being inserted while it runs?
