> I had one last month for their product web engineer role. They don't have recruiters at xai. It's the engineers in the team that filter resumes, call candidates.The first round was a short 15 mnts google meets call, the engineer went over what they are building - they are basically upgrading a legacy app built by twitter engineers years ago into react and looking for someone who has both react as well as react native skills. Received a rejection after the initial chat.
