The interview consisted of:

• 4 rounds
• 2 coding sessions
• 1 architecture session
• 1 behavior session

During each coding session, the interviewer asked two or more questions that needed to be solved very quickly.

In the architecture session, the interviewer asked a question similar to how to scale Facebook Messenger. The question was well-defined, but its scope was broad.

Given a list of the order of alphabets and a list of strings, return whether they match the order pattern.

Order: {'c', 'b', 'a'} Input: {"cbaa", "bb", "aa"}
