Microsoft Software Engineer interview questions

The interview process was really confusing. I was referred to Software Engineer Position 62 in Prague and heard back quickly, which was great. After the HR call they sent me a prep guide that said the technical screening would be 30 minutes and I expected a typical leetcode-style question. Instead, the interview lasted about an hour and focused on multithreading and concurrency, topics I wasn’t told to prepare for. I wasn’t ready for that at all. I shared my concerns with the recruiter, who brought in another recruiter, but no one ever followed up with me. I’m really disappointed. The interview didn’t match what they promised, and it seems like different candidates are getting very different experiences. For a company that says equity is one of their values, this didn’t feel fair.
