Interviewed with a company a few weeks back. Started with the technical, then got to the hiring manager two weeks later, and was told they'd give me a decision the week after.

At the end of the next week I reached out and was told they were waiting on manager approval due to OOO, and would get back "early next week". In the recruiter's reply they specifically used the phrasing "your offer details will be finalized" and said they would set up a meeting with me this week.

It's wednesday evening of the week now, and I still haven't heard from them. I am worried they are just trying to keep me complacent by dangling the offer in front of me while perhaps waiting on a better candidate in the background. Am I overthinking this? Or am I cooked?
