Nice interviewer with profeesinoal questions about statistic and cs. His personality is also good and full of patience to wait for me for the enough thing time. Btw the pantry is good with lots of yogurt and fruits.
As the technique round, the interviewee mainly asked two questions. Both of them are math questions. I am asked to derive the solution, and get the correct answer for it.
