I did a Zoom interview.
The interveiwer was kind and asked me some probability questions.

Question 1
Startegy of changing a line.
Is this a realistic strategy? What would change in the real world?
Technical interview round 1 and 2. Two math problems/brain teasers. Round 1 is easy, but round 2 becomes more challenging. Problems are well designed with multiple follow ups. Interviewer super friendly and nice. Great people and nice culture.
Very friendly interviewer and relatively easy questions. Quite organised in their interview process, with clear guidelines as to how to approach the interview. Focus is to explain the rationale and not just get the correct answer.
