NTT DATA Software Engineer interview questions

In 12 years of working in this industry, this is the single most ridiculous, rude, unprofessional behavior I've ever experienced: Waited for 30 minutes in the lobby after the scheduled interview time. Eventually someone showed up and took me upstairs. The interviewer told me my resume(which I had previously submitted) was too short and he didn't know what questions to ask me. He walked me to the elevator, pushed the 'down' button, and walked away with a perfunctory 'thanks' without looking at me or offering me a handshake. This entire sequence of events happened in less than 10 minutes. Absolutely absurd and unacceptable behavior. This is the epitome of what is wrong with recruiting / hiring.
