Intercontinental Exchange interview questions

very unprofessional. Interviewers did not show up on time. One interviewer took a private phone call while interviewing. No interest and no professionalism. Interviewer watching his watch constantly. did not answer my questions clearly. was not prepared to answer follow up questions

2 rounds of phone interview. The first one was about general questions about resume, two questions about C++, two questions about probability, one question about SQL. The second is about C++ and some brainteasers.
