I applied through an employee referral.

It was a 60-minute call. The interviewer was friendly and kind.

• 5 min intro
• 25 min algorithms on HackerRank (e.g., two pointers)
• 30 min ML questions in text editor (e.g., log reg)

I finished with a 5-minute penalty, and the interviewer said that I should answer faster.

Describe and write:

• Log reg
• Classification metrics
• Regularization
• Gradient optimization methods
