Yandex interview questions

I was asked to solve one simple algorithmic problem. Then I was asked questions related to the theory of machine learning, in particular about the algorithm of logistic regression. After the technical part, the interviewer asked me about my experience and told me about the company and the project

30 mins of theory, 30 mins for 2 whiteboard algorithms that should take at least 1 hour. Some extra time for candidate's questions. Sometimes it has a pre-interview section when you need to code algos online alone.
