My recruiter ignores me for 1.5 month after told me I got to the first round

I have applied for a Western Europe Mckinsey office.

After the SHL online test, the recruiter wrote to me that I pass to the next step in the process: 1st round of Personal experience interview and Case interview, that was at the end of April.

I wrote to him last week (1st week of June) after not hearing from him for 1.5 month, no response, and doesn´t pick up my calls either.

I simply just want to know if I´m still in the recruiting process or I´m already got rejected.

My suspicion is either he did some background check and heard something he didn´t like, or because I told him I´d like more time to prepare in our earlier correspondence (still doesn´t explain the ghosting...).

I have some distant contact in the McKinsey office, not sure if I should reach out to them...

Is there anyone know the recruiting process of McKinsey?

Thanks in advance!
