How can I land a job from an interview? I am having issues.

So, I need some advice.

I never had a job before in my life as it never was required. My parents never made me go get a job because they wanted me to focus on school. Get a very good degree, and go do a masters. Which I am doing but school is not for me and the market for tech is very bad right now so I gave up applying to tech jobs. (1 year of applying nonstop).

I have been applying to the basic entry level jobs. Like Admin Assistant, Tech Associate, and even some bank entry level jobs.

luckily for me, I managed to get an interview for an Admin Assistant Position (x2), and an interview for an entry level banking associate and some retail positions. As well as 3 coding interviews (i did bad on as it required an iq test)

Unfortunately for me, I did manage to pass the phone screening but failed the in person interviews, which is unfortunate but I tried my best.

The current job I have as a front is my commission based experience, bascially fiver where I interacted with customers and provided results and my 4+ year coding project where I led several teams in a project based enviroment.

I have been hitting 5+ interviews, and atleast have a few interviews every week but no luck on actually getting the job. I'm not sure what im doing wrong in the interview as its hard for me to tell or describe what I did. I tried to make my answers relevant to the job, and tried to sound confident. I wasn't nervous, I was fairly calm.

I showered before, wore business casual clothes, I had my hair brushed and had no makeup. My interviewer was in sweater and casual like clothing no suits. I was neatly groomed and was the best I could be. I wore a black blouse and black pants with black boots as it was snowing as well as a puffer jacket.....because as I said IT WAS COLD.

Any advice? How can I land my first job.

EDIT: I HAVE A DEGREE IN COMPUTER PROGRAMMING ( i love it sm and its completed) AND DOING A MASTERS IN CYBERSECURITY BUT I HATE CYBSERCURITY I WANT TO AVOID IT AT ALL COSTS. I dont want to go back to school, i want to find a job so i can provide for myself
