+1, it's been a while since I interviewed with Google, but this brought me back to how annoying it was. I've never had a good interview experience with Google. I only interviewed during college for internship and then a full-time new-grad role and got a consistent "we're doing you a favour by even talking to you" attitude from them— the delays, the impersonality, the delays to the general vibe of the emails, etc.
They became significantly more attentive when I got an internship offer from a competing big-tech company, but as much as my recruiter seemed to try, the process just seem to be deficient beyond their capacity to do anything about it. It had to go through many steps, and be reviewed by many people who seemingly had better things to do.
Eventually they reached to the right people to tell me my decision before my other deadline. I _was_ going to get an offer. They couldn't get me the actual offer letter, or tell me if I had guaranteed host-matching though. I happened to know Google can send intern offers that don't guarantee you'll be matched to a team, and if you're not, the internship just doesn't happen. In my book that's not only as good as no offer really, it's also just disrespectful. I knew people who had this type of offers and didn't get teams.
I took the other offer. "You will get an offer, the details are just taking a while" is not enough to decide on, and the whole process didn't particularly warm me up to Google. For comparison, and to give credit where credit is due, the other company was Meta (then FB). My recruiter was very response, understanding, and personable, which is especially appreciated as an college student— you're nervous, unexperienced and have a lot going on beyond interviewing. They sent me pictures of their dog to lighten the mood. I had told them I'd appreciate quickness, and by the time I was eating dinner after my on-site, I had the offer letter in my inbox.
