Honestly I’m 100% with the you’re over reacting brigade. 11 days is really not very long.
I know the job hunting market is shit right now and there is lots of bad practice and ghosting going on, but the expectations shown here are ridiculous. I guess it’s cos most people have never been on the other end of the recruitment process. Honestly it’s nightmare for hiring managers too. It’s frustrating that they indicated one timetable and haven’t stuck to that, but that’s not unusual. Like people said it could be all sorts of reasons: another candidate has had to postpone their second interview, they are having trouble getting diaries aligned for the 3rd round interviewers, people are off sick, on holiday. Even Something has changed in the business and they aren’t sure if they are even still recruiting for the role!
it’s poor of the recruiter not to keep you updated, but in some of those scenarios they may not know what they can tell you. They may not know themselves. And they are undoubtedly swamped dealing with the flood of AI slop applications you have to deal with for any job posting these days.
send a calm, professional follow up email, reiterating how keen you are in the role, and any key points about how great a fit you are, and ask for an update. If you don’t hear anything in another couple of weeks send a last, polite follow up. Then drop it.
and yes, it might be that you aren’t in their first round of 3rd round interviews, but you did well enough that you are not a firm “no”. In which case the last thing you want to do is blow your chances here by coming over as unprofessional!
