TeleGeography interview questions

Communicated and set up through 3rd party recruiting agency. Met with Customer Success Team leader, great conversation. Moved to 2nd stage of process, written portion and was given access to their internal product website. Submitted written portion, which would be discussed on next meeting with the account manager. The meeting was cancelled an hour before the meeting (extremely unprofessional) after reviewing the written portion and proceeded with other candidates. No feedback or communication.
