Interview with Cohesity for Senior Security Software Engineer

Hi,

I applied for that role in Linkedin and got a call from HR
1st round: Call with recruiter to ask about my experience and expectations.
2nd round: With Hiring manager - Typical behavioral interview questions and some technical questions.

Then I received a call from Recruiter to schedule all 3 interviews in a week.

3rd round: Domain interview deep into technical questions related to Security and Software engineering.
4th round: Security System Design interview - It was more fun.

So now, after the 4th round I was waiting for the 5th round to happen but all of a sudden, the recruiter calls me to inform that the 5th round has been canceled. I asked her why but she did not give me any straight answers to that and she said that she is unaware why the 5th round has to be canceled but she was informed by another recruiter that it needs to be canceled and that's all. She also mentioned that she will get back to me.

So what does it mean? Could anyone please tell me? This is giving me a very bad feeling that they will not conduct the 5th round though they scheduled all last 3 rounds at once. Has this happened to anyone while interviewing with any other company?
