This is absolutely legitimate. I was approached by a Google Rep and completed the series of tests for the $5 gift card. Mostly out of curiosity to see what they’re up to.

I went through all of the poses one would do if they were training a model to perform similarly to FaceID. (Ok, now pull the phone out of your pocket and look directly at it. Look up at me then down at the phone, etc.)
