Technical Presentation
Technical interview with two members of the Data Engineering team, and the feedback was absolutely negative. Arrogance at its finest. They criticize my master's thesis explanation, not really talking, but making faces and giggling. After I point out my feedback about their behavior, one of them makes an excuse that he has experience in that field and my results seem strange to him (as if he didn't know that results definitely depend on the dataset you had available..). I explicitly asked to be removed from the candidate database.
Confirmed questions3 questions
- Master's thesis
- Database structure
- Python quiz
