Boston Consulting Group Analyst interview questions

Good, it was a recruiter call for BCG X and there were basic questions but did not exactly know why I was rejected, she asked about my background, skills and sponsorship

It was on Jan 2024, I had easy first recruiter call but couldn't fullfill all the requirement they wanted C# knowledge must. They asked basic tell me about yourself questions and few questions specificly for the position such as how many years of experience, knowledge of SQL and C#
