1. HackerRank OA, 75 minutes, 2 questions. I used an O(n^2) algorithm for the first one and exceeded the time limit for a test case, but still managed to pass to the final virtual onsite round. (Talked with the recruiter for 30 minutes about the interview.)
2. Virtual onsite, 1 hour probability & machine learning and 45 minutes behavioral. Just finished; might come back and edit.

OA:

• One longest interval with a sum limit.
• The other is string parsing and hashmap.

Probability technical:

• The classical Seattle raining problem.
• Uniform sphere sampling from a uniform distribution.
• Expected number of times of two consecutive coin heads.
• Logistic regression gradient descent from scratch coding.

Behavioral:

• Talking about previous projects.
• What if you disagree with a supervisor?
• Asking for help or solving by oneself...
