Is LinkedIn's "Your Application Was Viewed" Notification Reliable?

Hi everyone,

Is the "Your application was viewed" notification on LinkedIn accurate or meaningful? I applied for a position back in February and went through four extensive interviews. However, they stopped responding to my thank-you letters and follow-up messages about four weeks ago. Today, I received an email from LinkedIn saying, "Your application was viewed."
I'm not sure if this is accurate since I have the impression that they passed on me. It's a big company, so I doubt they're reconsidering my application. Any insights?

Thanks
