Microsoft Senior Software Developer Engineer interview questions

I talked to the recruiter for about half an hour. We set the date for the first round of online interview in a few weeks. The interview was for a position in Azure Cloud Storage team. The interviewer asked a very tricky question from Cracking the code interview and he was silence for about 30 minutes. No hint, no nothing.
