Microsoft Senior Software Developer interview questions

Having interviewed for a SDE role in the US prior I expected a similar level of professionalism especially from the likes of Microsoft, however this was not the case. I was approached to take a online interview/technical screening which went well, I correctly answered two coding challenge questions no problem. However there was a network related question which I found quite odd as the job description didn't call for any of that type of knowledge, I was upfront but answered as best I could (and in all honestly I checked the question against my answers later and I wasn't actually that far off). After the interview there was basically no contact from the recruiter(Philippines based) unless I prodded constantly for feedback/result of the interview, and even then he would only try offload to someone else. I finally got some feedback after clicking the "Contact Recruiter" button on the Action Center page and surprise surprise it went to someone local who told me I failed due to the network question (again, not on the JD).
