Nasdaq: GILD

Gilead Sciences, Inc. is a US biopharmaceutical company founded on June 22, 1987 by Michael L. Riordan and headquartered in Foster City, California. It trades on Nasdaq under the ticker GILD and is a component of the S&P 500 and Nasdaq-100. The company describes its mission as discovering, developing and delivering innovative therapeutics for people with life threatening diseases.

The business is built around three therapeutic areas: virology, oncology and inflammation. Gilead is best known for its HIV franchise, which includes Biktarvy and Descovy, and it has expanded into cell therapy through Kite and into antibody drug conjugates with Trodelvy. In June 2026 the FDA approved Trodelvy for first line treatment of metastatic triple negative breast cancer, and Gilead and Merck reported positive Phase 3 data in July 2026 for a once weekly oral HIV regimen combining lenacapavir and islatravir.

Gilead employs more than 17,000 people and operates in over 35 countries. Reported revenue was $29.44 billion for fiscal 2025, and market capitalization stood at about $161.8 billion in late July 2026. First quarter 2026 revenue reached $7.0 billion, up 4% year over year, with total HIV sales up 10% to $5.0 billion. The company has been actively acquiring, closing the $7.8 billion Arcellx deal in April 2026 and agreeing to buy German ADC developer Tubulis for $3.15 billion upfront.

Gilead Sciences Interview Questions & Answers

Q: What experience do you have with biologics?

A: Walk through the modalities you've handled and the assays you ran on them, then tie that to QC release or stability work. Keep it concrete: molecule type, your role, the method, and what the data was used for.

Answer by AI
  • Name the modalities you've worked on, such as monoclonal antibodies, fusion proteins or cell therapy products, and say how long you spent on each.
  • List the analytical methods you own end to end, for example ELISA, cell based potency, HPLC, capillary electrophoresis or qPCR, and mention GMP versus research context.
  • Close with one result: a method you qualified, an investigation you closed, or a release decision your data supported.

Q: Did you work with PMOs or CTLs before?

A: Say plainly whether you have, then describe the working relationship rather than just the acronym. If you haven't, describe the closest cross functional partner you've supported and how you handled their timelines.

Answer by AI
  • Answer yes or no first so the interviewer isn't guessing, then give context in one sentence.
  • Describe the cadence you worked to: intake requests, status reporting, escalation when a timeline slipped.
  • If you lack direct exposure, name an adjacent partner such as manufacturing, regulatory or a clinical operations lead and explain how you'd ramp up quickly.

Q: Do you have regulatory affairs experience?

A: Be honest about depth. Most QC scientists contribute to filings rather than own them, so describe what you actually supplied: method sections, validation data, deviation write ups or responses to agency questions.

Answer by AI
  • Separate what you authored from what you reviewed or contributed data to, and don't overstate ownership.
  • Name the frameworks you've worked under, such as GMP, ICH guidelines or FDA and EMA submission support.
  • Give one example of an audit, inspection or query response you were part of and what you learned from it.

Q: Do you give tours and presentations at your current job?

A: They're checking whether you can represent the lab to outsiders. Say who your audiences have been, how often, and how you adjust the level of detail for a non technical group.

Answer by AI
  • State the audiences: new hires, auditors, visiting partners, or leadership reviews.
  • Mention frequency and format, for example a monthly data review or a walkthrough during client visits.
  • Explain how you shift depth for the audience, keeping the method detail for scientists and the outcome for everyone else.
