Experience - Biochemists and Biophysicist
  • Designed and optimized enzyme kinetics assays (Michaelis-Menten, IC50) for a small-molecule inhibitor program, increasing throughput from 24 to 96 samples/day using plate-based fluorescence reads and automated data fitting in Prism.
  • Built and validated a recombinant protein expression and purification workflow (E. coli, Ni-NTA, SEC) producing 50-100 mg/week at >90% purity, enabling structural and binding studies across 12 variants.
  • Characterized protein-ligand interactions with SPR and DSF, generating KD values (5 nM-20 uM) and stability shifts that guided medicinal chemistry and reduced off-target binding by 30% over two design cycles.
  • Developed a cell-free biophysics panel (CD spectroscopy, DLS, thermal ramp) to flag aggregation-prone constructs, cutting failed downstream experiments by 40% and standardizing QC reporting in ELN for a 6-person team.

Interviewer
Can you walk me through a project where you improved assay performance and what impact it had?
You
In my last role I redesigned a fluorescence-based enzyme inhibition assay by tightening substrate ranges, adding internal standards, and automating plate setup, which improved Z' from 0.45 to 0.72 and moved us to a 96-well format that doubled weekly compound coverage.
Interviewer
What do you do when SPR or binding data look inconsistent across runs?
You
I start by checking immobilization levels and reference subtraction, then run a concentration series with fresh analyte prep, confirm monodispersity by DLS, and use orthogonal methods like DSF or activity-based IC50 to verify the interaction before concluding it's a true weak binder or an artifact.

Why practice first?

Interviews are high-pressure

Even strong candidates underperform without reps. Practice reduces stress and sharpens delivery.

Rehearsal builds muscle memory

You get comfortable telling your story, quantifying impact, and handling curveball follow-ups.

Feedback accelerates improvement

Immediate, actionable notes help you close gaps before the real interview.
