There are so many variables. It could be an indication of a manager who struggles with time management, organization and prioritizing. It could also me she's a manager who is organized and prioritizes and interviewing isn't top of the list right now. It is very difficult to decipher an intention from one behavior. If it's a role you're interested in, it doesn't hurt to go on the interview and keep your antennae up for clues of management style. It's a first interview, if nothing else, it provides experience. Good luck.

I'd say that the amount you pursue it depends on how much you feel that this role, and this organisation, are a good 'fit' for where you are now, and how you want to grow in your career. If your application for the role is based more on geography (close to your parents), then perhaps don't follow up. But if you think it's a good fit for your skill set and career aspirations, follow up again with another email and phone call. In either case, I wouldn't withdraw the application - just in case there was a compelling reason why she didn't touch base with you. She might just be busy, or unwell, or have a family emergency. Doesn't necessarily indicate that she'd be a less-than-ideal manager. At the same time, I'd keep searching and applying for other roles. All the best!

I'm sorry to hear that you're going through this, as I know how frustrating it can be to have someone express interest in interviewing you, and there being a long delay before they get back to you. My hope is that the hiring manager is just really busy and hasn't had a chance to get back to you yet to schedule an interview. Given the number of people out of work right now, she may also be inundated with/overwhelmed by a large number of applicants. Either way, though it's possible a lack of follow up is indicative of her management style, there could also be myriad legitimate reasons that you haven't heard back. Before you withdraw your application, if there's a chance that you can contact the recruiter again to follow up and see what the delay is, you might try that approach before completely giving up. Hope it all works out for you!
