Microsoft Senior Engineer - Software Development interview questions

I was asked at 8:30 for a hiring event. Had the first round from 8:45am, it was about Data Structure and problem solving. I solved the problems and further variants, thought it went excellent. Then had to wait almost an hour before the second interviewer came. He himself said he wasn't prepared and it was a last minute. Then he proceeded to ask a math related coding question. I couldn't remember the property so I needed help, then it turned out the actual algorithm/coding needed was almost trivial. Again I waited an hour without any information and then called up the recruiter and was asked to go for lunch. After lunch, I had a Systems Design round. We started from generic problem to more designs. I thought it went well. The interviewer did say the they didn't have feedback from 2nd round yet, only 1st round. After this, I waited a few rounds and was told the feedback wasn't positive and I am pretty sure it was the feedback from 2nd round and I just had to waste a few hours more due to lack of coordination on the recruiters' part. I should mention that the interviewees were polite and nice to talk to.

Got a phone call first then an email to schedule an on-site interview. Took half day for meeting with 5 people. Each interviewer spent 30~60 minutes asking questions about my past jobs and asked me to do some coding on paper. Interviewers are smart and friendly people. Overall the experience is enjoyable.
