so, basically I'm just looking for confirmation on something I'm already fairly sure of here, but I thought I'd ask. You have a callback with a firm and they tell you at the callback that they'll probably get back to you in mid-September. It is now almost October. Is it safe to assume you will not be receiving an offer? I'm fairly confident that is the case, but I thought I would check so that I can have my hopes officially dashed.
Go ahead and call the employer to follow-up. There's nothing wrong with that.
