interview timeline

hello ladies and gents,

i got a call from a google recruiter for a senior software engineer role and was given an interview window of 31 march to april 4. the hr said that the scheduling team would reach out by march 24.

while the hr contact did arrange a super helpful mock interview on my request (which went well) on march 28, i still haven't received any communication about the actual interview even though the interview window has passed. i've followed up with the hr during the window from 31 march to april 4, but haven't received a response.

any idea what's going on behind the scenes, or any advice on how to move forward?
