To excel in the Natera interview process, you must understand the specific technical and behavioral dimensions on which you will be evaluated.

Technical Presentation & Scientific Communication

Your research seminar is the single most critical component of the panel interview. The team evaluates not just what you accomplished, but how you communicate complex data to an audience that may not be experts in your specific niche.

Be ready to go over:

• Experimental Design – Clearly explain your choice of positive and negative controls, sample sizes, and statistical methods.
• Data Interpretation – Be prepared to defend your conclusions based on the data presented on your slides.
• Q&A Handling – Expect direct, sometimes challenging questions about your methodology, and answer them with confidence and scientific humility.
• Advanced concepts (less common) – Multiplex assay optimization, library preparation chemistry variations, and surface chemistry of sequencing platforms.

Example scenarios:

• "Walk us through the slide detailing your assay's limit of detection. How did you determine this statistical threshold?"
• "If you were to adapt your academic research into a high-throughput clinical test, what would be the first three steps you would take?"

Molecular Biology & Assay Design (NGS/PCR)

As a Research Scientist, you must possess a deep, practical understanding of nucleic acid manipulation, amplification, and sequencing technologies.

Be ready to go over:

• PCR Optimization – Primer design, master mix components, thermocycling profiles, and troubleshooting common artifacts like primer-dimers.
• NGS Workflows – Library preparation, target enrichment (hybrid capture vs. amplicon sequencing), and sequencing chemistries.
• Cell-Free DNA Biology – The unique physical properties of cfDNA, including fragment size distribution and low concentration challenges.
• Advanced concepts (less common) – Unique Molecular Identifiers (UMIs) for error correction, methylation-specific PCR, and digital droplet PCR (ddPCR).

Example scenarios:

• "How would you design an assay to detect a single nucleotide polymorphism (SNP) present at a 0.1% variant allele frequency in a background of healthy genomic DNA?"
• "Explain how you would troubleshoot a sudden drop in library yield across multiple clinical samples."

Critical Problem-Solving & Experimental Troubleshooting

Natera values scientists who approach failures systematically rather than using trial-and-error.

Be ready to go over:

• Root Cause Analysis – How you isolate variables when an entire assay fails to perform as expected.
• Data-Driven Decisions – Utilizing statistical tools and pilot studies to validate troubleshooting hypotheses.
• Collaboration in Troubleshooting – How you leverage bioinformatics or software teams to resolve complex assay anomalies.

Example scenarios:

• "Describe a time when you realized your experimental results were skewed by a systematic bias or batch effect. How did you identify and correct it?"
• "If your positive control fails to amplify but your samples show weak signals, what is your immediate troubleshooting workflow?"

On a day-to-day basis, a Research Scientist at Natera is responsible for driving innovation at the bench and translating those discoveries into clinical applications.
