Hi Ajay. For part of your questions, I have answered just above. Please scroll back and check.
For the next set of questions, in my experience the interviews usually happen during the week days (they called me on a Wednesday morning at 11.30am and my sponsor on a Thursday afternoon), but the online status changes can happen any time (weekends, mid-nights, early mornings, etc).
The overall interview time-frame can be anywhere between 10-20mts. See, again it depends on the officer and the applicant. If the officer wants to know more about you then the time frame can extend and viceversa. For me, he interviewed me for nearly 18mts. He was pretty cool except that he had a whole bucket load of questions for me. lol. I answered all his questions and in the end he seemed to be satisfied. Remember to have a straight neutral voice and talk slow so that the officer can understand. Good luck
