All i found out is the first interview is short, especially after passing 2 stages. The 100 first interview was mentioned by someone as an example. Some organisations like to interview before sitting any tests, others like to sit tests first. Generally ones that sits tests first end up interviewing a much smaller group, as the tests were designed to isolate the group deemed suitable, and the interview just to affirm this. Which might explain the short first interview with dragonair. Or it could be they interview so many people they keep it short hahaha
