I applied online. I interviewed at BillionToOne (Menlo Park, CA) in Jan 2026
Interview
First I was asked to take an assessment which included 7 biology questions (in 10 minutes) and 9 technical questions in (13 minutes). After this there would be an interview but I am at the first stage right now.
Online skills assessment via TestGorilla. Was asked basic biology and coding questions. Bash, Python, R, SQL were languages covered. For biology it was basic genetics questions (AP Bio Level) and a question about PCR.
