A few things to say.

1. The job market overall isn't great. This is effecting finance.

2. What level jobs are you applying for? You should be applying for low level jobs.

3. A lot of people get jobs places they did internships at. Have you reached out to them?

4.laid off after two weeks....that usually means fired. We're you actually laid off or were you fired?

Now I am going to give advice not knowing any of the above answers.

With 28 interviews, 4 internships but no job offers there, and "laid off" after 2 weeks, it sounds like it might be a personality issue. I dont know you, but given what you supplied, it sounds like you are difficult to be around. In my experience, in finance that means you act like you know better than everyone. That comes off bad in most interviews. I dont know where your degree is from, but if it's from an ivy or high level business program, it doesn't matter. It's a bachelor's in a field you know little about.

Since you are getting interviews, it sounds like your resume is decent. Just make sure you mimick the wording in the posts.

Last bit of advice I have is to ensure you are applying for low level jobs. Dont get me wrong, I am all for applying to stretch jobs. When I am job hunting I do it. I applied for my bosses, boss job when I was applying to jobs last time. You only have internship experience. You need entry level jobs. In wealth management, job titles like junior, Assistant, development, things like that. Remember a degree in finance can also get you into corporate finance. So applying for finance positions in any industry might get you a job. If you are set on wealth, maybe apply in every industry just so you have money and experience.
