One of my more junior teammates got their CL assigned to Sanjay for review, she had no idea who he was and I just told her to look at all her new badges tomorrow.
I've never had in for a review at google, I think it only happens if you change something very top level. I did an internship under him the summer before he joined Google at Dec/Compaq SRC though. I learned a lot of tricks from him then (like using graphviz to print out compiler graphs to do debugging).
