The interview questions candidates score worst on are not the ones they prepare for. Real data from 816,000 sessions explains why.
Short summary
Analysis of 816,000+ real interview sessions reveals candidates score lowest on behavioral questions they skip in prep—"Why do you want to work here?" averages 25/100—while over-preparing for technical problems. Senior engineers underperform, while PMs score highest due to structured behavioral training. Behavioral questions get <5 minutes of prep and generic answers fail to demonstrate fit.
- •Behavioral questions score 25-45/100 despite candidates ignoring them in prep
- •Technical question mastery doesn't correlate with success like behavioral frameworks do
- •Senior engineers surprisingly underperform; PM culture emphasizes STAR-method storytelling
