Just playing and learning a bit about MBTI. A bit surprised that all 16 types are in the story 😅
Dmitry: INFP
Alexei/Vitaly: ESFP/ISTP
Vadim: ISTJ
Vasily: ESTJ
Fyodor: ISFP
Oleg: INTJ
Anatoli: ESFJ
Semyon: ENTP
Andrei: ISFJ
Stepan: ENTJ
Ivan: ENFP
Maxim: ESTP (Unhealthy)
Then for real life people, I was more to guessing based on how much I have developed them in project and how the ensemble describe them in biographies.
Boris: ENFJ
Vladimir: INTP
Alexander Jr: INFJ
I don't imply the type for Alexander Vasilyevich since I don't know much about him.
