FIRST ROUND:

It felt like the interviewer was not at all interested and unprepared. The questions she was asking were so vague and stupid. I had to ask her multiple times to please clarify exactly what she wanted, but she kept repeating the questions.

She asked me to describe my work at my previous company. When I answered, she was just dismissing my answers, saying, "Is that all you had to do?" Who does that?

It's not like she was some expert or anything. All her questions were so stupid, and any answer I gave didn't apparently satisfy her. I don't know what she was expecting.

For example, she asked what data structure I would use to store an incoming bunch of data: a List or a Set.

I told her it totally depends on how we plan to use it. For a lot of insertions and retrieval, we could use a Set, but if it's sequential, we would use a List. I asked her if we had more information on what we planned to do with that data. She had no clue. She kept repeating the same question again and again.

After everything I explained about my work, she basically summarized my work by saying that all I do and all I did for the past 5 years was just "XML parsing." What kind of people do they send to interview others in this company? A very negative experience. It's as if everything I prepared for the past week was a waste of time.
