Well, I translated the interview using Google Translate, here are the most interesting sections.
The most challenging jump for Polina was the flip
This surprised me, I did not know that this was a problem jump for Polina - at RusNats she nailed this jump twice! It seems that many skaters are strong with either the Lutz or the Flip, but not both. Here is a rough translation:
"The flip - it was the most terrible jump for me; The first three months after the move [to Eteri Tutberidze], we just fought over this jump. I could beat him for half an hour, for 40 minutes in training, to fall every time - and all for nothing. At first I had a purely psychological fear of this leap, but then the fear passed from repeated repetitions, and the leap began to turn out. Flip, probably, was the beginning of my victories over myself."
After figure skating, Polina wants to become lawyer
Polina says that her goal in figure skating is not specific (such as going to Olympics), but rather to give her best effort. Polina mentions that her parents and she are looking for a law school and that she is very interested in lawyer TV shows
Polina stays with Buyanova
Polina mentions that during the pre-season, Buyanova focuses much more on skating skills and step sequence than Eteri Tutberidze. (Although, jumps are never forgotten...

) However she mentions that her back soreness is still impacting her choreography classes and hall exercises. She is happy with Buyanova and she will keep fighting.
Overall it seems that she is in good mood still despite her comparatively lackluster season, here's hoping Polina all the best!!!
P.S. Do any of you know if Polina has any more competitions this season? Couldn't find any
