Domande di colloquio per MTS - Software Engineer presso NetApp

I received a call from NetApp for the initial discussion on work experience, expected salary and things like these. They scheduled an interview, cleared this round. On the next business day I got a call for next round. I'm assuming third round is the HR round.

FIRST ROUND: It feels the interviewer was not at all interested and not prepared. The questions she was asking were so vague and stupid. I had to ask her multiple times to please clarify exactly what she wants but she kept repeating the questions. She asked me to describe my work in prev company, and when i answered she was just dismissing my answers saying "Is that all you had to do"...Who does that? Its not like she was some expert or anything. All her questions were so stupid and anything answer i gave didnt apparently satisfy her. I dont know what she was expecting. Ex: She asked what DS will i use to store an incoming bunch of data. List or a SET. I told her it totally depends on how we plan to use it. Lot of insertion and retrieval we can use SET but if its sequential we use LIST. I asked her if we have more info on what we plan to do with that data. She had no clue. She kept repeating the same question again and again. After everything i explain about my work, she basically summarized my work by saying that all I do and all I did for past 5 years was just "XML parsing" . What kind of people do they send to interview others in this company. very negative experience. Its as if everything i prepared for past 1 week was just waste of time.
