Did my interview go well or fail?

It was scheduled to last 45 mins, but only lasted 35. Does shorter time mean I performed badly? Felt like a nice conversation, and we laughed. Most my answers were good and he even praised me a few times saying that's the first person we've heard that etc etc.

I had it last Wednesday and haven't heard back since.

How long do they take to get back to you post interview?

Also I noticed on LinkedIn the job was reposted? Does that mean I failed? It is a large firm so maybe linkedin auto renews?

Any advice?

In total they asked around 9 questions, some of which were general getting to know me question, some were behavioural.

I also noticed him say, "you" alot like he said you would be expected to come in 5 days a week etc.

I don't think finishing an interview ahead of the allocated time is a bad thing. Sometimes ot means you've connected with a panel and have given a good and thorough account of ghe wuestion and they may not have needed to follow up with and supplementary questions. I think believe how you connect with your interview panel is just as important as answering questions.

I always believe that when a panel member gives descriptions of a job role or duties and place "you" in the conversation and not " the successful candidate" in the conversation, they aare picturing you in the role.

Sucessful or not, always get feedback.

Goodluck
