Yandex interview questions

I have applied online through the website. Recruiter called the next day. After that recruiter scheduled Tech screening. After that there were 4 virtual onsites each around 45-60 mins. You can ask questions at the end of the interview. There were 3 coding and 1 system design interview. Upon clearing onsite there were team matching sessions. Recruiter gave feedback after each session.

The interview lasts 1 hour. You get 2 algorithmic problems - simple and medium in complexity, and you need to write a solution without bugs. The interviewer can give you a hint if you need it.
