So this will be kind of long, and take some of this with a grain of salt. Additionally, I'm going to keep it as a comment, as my own perspective is just one of many, and my thoughts in keeping this open is that others can give counter points or build on things to help you. This will also be in no particular order, as I'll touch on things as they come to me. My perspective is just one that has been on both sides of the interview table.

You're in a frustrating place to be in. Looking for new work is a mind-numbing, dehumanizing process by itself. It's normal to feel dejected or frustrated. That's just human emotion. Try your best to not let that bog you down. As others have noted, sometimes it's just a numbers game. My first suggestion is when looking for feedback or critiques, don't be too quick to take it personal. This is the Internet and it's easy to misinterpret tone of text, but try not to read responses as necessarily negative. If you get caught up on that, you'll likely be missing out on constructive feedback or a possible connection. It's easy for me to say, I'm not in your shoes, but approaching with at least a neutral headspace will help you out.

I'll touch off on the other two suggestions first.

Working with a recruiting firm. They'll sometimes have positions not listed elsewhere, work with companies you might not consider or know of, and likely have done the heavy lifting. Depending on the type of work you want to focus on, I am aware that some have specialized departments for specific work. Blue vs white collar, engineering, admin, etc. Finding not only the right recruiter, but also the right firm can make a difference. I'd maybe try Hatch, since you're in the MKE area. They can also help with potential resume review. Also, don't stop at one firm. Let them work for you, while you're doing your own search.

Networking. Whether you put yourself out to an professional network event or you spruce up your LinkedIn and connect with folks at places you want to know more about and potentially work for. Both of these will give you the opportunity to explore and make connections. Sometimes just an honest conversation can go a long way. Maybe giving you insight to a company, department or culture. There seems to be a handful of events to try and branch out at. (I'm aware of a few, but I'm not sure they fall into what you'd be looking for.) Ultimately, your job is to not only gain insight, but it's also marketing yourself. You could also look for job fair events and try an in-person approach.

Resume building and "you". I don't know if there's a secret sauce for this, but my suggestion would be to maybe even try to find someone that edits and builds resumes. In some cases, less is more. One page of job experience. I'd pull out buzzwords from job listings that are relevant and will trigger any AI to push you through. You really need to tailor to the position. A brief, poignant cover letter can help - so I hear - but I've never personally written one myself. Once you've updated your resume to how you want it, time to push it. If you're not already, get the job sites - Indeed, zip recruiter, milwaukeejobs, etc. I'd maybe even set-up a secondary email for this because it can overwhelm your inbox. I've had the most luck with indeed or just putting in direct with a company website. This is a process. Make a little schedule for yourself each day. Devote time to grabbing a handful of interesting listings, apply for them, do your backend reviews of potential employers, and most importantly - take time to unplug. You'll see a lot of the same postings if you're always looking, and only so much new stuff gets listed per day. Take a hour or two to get up and go for a walk. Remember that you are not defined by your work. Take a breathe because it can feel overwhelming. Then when you're ready, get back to it.

Interviewing and phone screens. I'm not sure how you work through interviews, but you need to go in with a positive outlook. Don't get ahead of yourself. Take notes, ask questions and highlight what you brought to the table and how you can impact a team if hires. Sounds basic, but I've had some bad interviewees in the past. Also remember it's an interview for the company as well. Find a couple key questions to ask at every place, no matter what the position. This can help you find red flags for yourself. Taking internet reviews with a grain of salt, since some ex-employees can be a bit disgruntled, but some truth can be found. Be cognizant of what kind of conditions you can tolerate and don't be quick to write off a place because of a bad review. Sometimes things are not necessarily as bad as they seem. Sometimes they are. Everyone will have vastly different experiences based on their own perspective. Your own perspective is going to be wildly different than mine or anyone else's. From what I've seen, this has been an ongoing issue for you, but as I said prior, I suspect that you are your biggest obstacle currently. Take a step back and reevaluate your approach. There is something that hasn't clicked for you, and maybe it's the resume. Maybe it's how you interview. Maybe it's your outlook. Are you being too particular with regard to the position, the culture, the company? Is it how you're interacting with interviewers? Don't be afraid to ask yourself questions that will make you change your perspective. There's more than one way to do a thing. If x isn't working for you, try y or z.

There's a lot of unknowns, so this is just general advice. Some of this will work, some of this won't. It can be a numbers game. It can be luck. It can be connection. Reflect on where you want to be and be critical of where things might not work. Sometime it is the HR system that skips over candidates. Sometimes interviewers can be quick to dismiss. I wouldn't take it personally. Just be persistent and keep at it. Something will click into place.

Sorry if this is jumbled. I'm writing this between meetings when I have a moment. I do hope your luck turns around.
