Technical

The interview was mainly about technical stuff, especially different models and when to use them. They asked me to pick models for specific situations and explain my choices. It was a good chat and the manager was nice, making it easy to talk. Overall, it was a good interview that really tested my technical knowledge.

Technical Coding Behavioral

The interview started with a 1-hour round focusing on ML and stats knowledge. The second round, lasting about 4 hours, covered resume discussion, technique questions, and a live coding exercise. The first interviewer was nice, but the second one was offensive, questioning my math major's relevance and poorly framing questions. He also kept dismissing my suggested models and the coding problem had a typo. Instructions and formulas were given in Excel, requiring translation to Python, which was a bizarre experience with that interviewer.

Technical Behavioral

We had a first round phone interview where they asked basic questions to check my availability and some stats questions like p-value. Then, a second round video interview focused on tech questions, mainly probability (like the coin slip problem) and ML models (pros, cons, and differences between decision trees, random forests, boosting, PCA, etc.).

Confirmed questions2 questions
  • Could you define Type I and Type II errors and explain model power?
  • What are Type I and Type II errors and the power of the model?
