You emailed them right before a holiday weekend. I know I'm always rushing to finish important tasks at the end of the week before a holiday. And are you sure the people you emailed are even in the office today? I know you are probably anxious and stressed, but it's completely unreasonable to expect a reply that quickly. It has been 6 working days since your interview, and not even one since your last email. Don't let your anxiety take over and sabotage you. You are also reading way too much into the repost - sometimes this is automated, sometimes it's reposted by someone who has instructions to repost jobs that aren't filled yet no matter where they are in the interviewing process. And it's not even the job you were applying for. You are being unreasonable.

If you are misinterpreting this, because they were too busy to reply on Friday and out of the office today, you are going to sound completely unhinged and may take yourself out of the running with this. You can always write a bad review later. You can always follow up with HR later. Keep applying elsewhere.
