X Financial Analyst interview questions

Recruiter reaches out to you, hiring manager then reaches out, if you pass that then you get sent an excel based test. After that is the in person interview, which was the worst candidate experience I have had. I was really excited to interview at Twitter because of the product and leadership. My first interviewer was over 10 minutes late, second was 15 minutes late, and third was 15 minutes late. The fourth did not show and I was sitting there for 40 minutes before I was approached y recruiter letting me know that the others were pulled into an emergency meeting. I understand the meaning of this as the decision was made to not move forward with me, which is completely fine. However, to keep someone waiting there for 40 minutes before letting them go is completely unprofessional. Please have more phone based interviews to decide if there is a mutual fit. Otherwise, this is a waste of everyone's time.
