Trella interview questions

very bad, the interviewer (member of the product team) was unprofessional and unwelcoming at all, she was not answering any question of my own and was allowing focusing in asking multiple questions and giving a sardonic expression after I say my answer. I don't know why it was this way, I believe that a lot of people are very good at their companies, but maybe they are not the best when it comes to interviewing another people .
