Interview questions are very basic during the first half of the whole recruitment process. They ask about you and your experience, and they try to gauge yourself as a leader in general, as well as your work ethic. 1st Interview is basically about your resume, 2nd Interview is with more questions about concrete work experience. Interviews last very short, around maximum 20-25 minutes. They somewhat tend to repeat the same questions throughout the different interview stages, and as much as you could repeat what you said before, it would be better if you said something a little different each time to make yourself stand out even more. They inform you whether you passed to the next stage or not, which is the barest minimum, I guess. When you pass, they send the emails a little later than what they promised/informed you (in my case). When you're rejected, emails are scheduled and sent on the very day they said they'll release results. When asked for feedback regarding your interview (of course, you'd want to know why they rejected you, normally), they don't bother replying, despite opening your email.
