December filer go an interview scheduled

Hi… my wife and I filed for AOS back in Nov last year and gave biometrics last December. Once our priority date became current, I filed for the I-140 premium process and was approved. I’ve been monitoring USCIS’s API and saw that 2 FTA0s appeared after the i140 was approved, and just this week we received an interview-scheduled notice.

I wanted to ask whether getting EB2-NIW interviews is more common? I saw that a few Redditors mentioned that if the primary has a derivative mentioned or the marriage is less than 2 years old, it's common to call for an interview. What do you think?
