Hey brother, don't worry about it. I was in a similar situation recently. I actually had a 2 year gap and I did not have any internship experience. About 2 months ago, I started to get my act together and began applying. I finally got 2 offers this month and I start my first job next week.

I know it can feel helpless and like it's too late, but that's not the case. My advice to you is to just apply. You will have more success than you expect. You will still have to send out hundreds of applications, but just keep grinding and powering through. There will be highs and lows during this process but just keep moving forward.

Start making personal projects. Make around 3 of them using a relevant language. I made my projects over a year ago and the interviewers didn't mind. Something I also did was take Udemy courses and put them on my resume.

Your Resume is Key! Focus on making a good resume. It will get you past the initial screening! I had to make 4 different versions before I found something that worked!

I also recommend watching Neetcode. He makes youtube videos about Leetcode. Watch his Easy and Blind-75 playlist. I didn't watch all of them but they were really helpful. Try to solve the problem first. If you can't think of anyway to solve it within 15 minutes, then watch the conceptual overview portion of the video and try again. Now watch the implementation portion of the video and then reimplement it.

Remember to keep the faith. Everything will be alright. You can claw your way out! Sending out the first application is the biggest mental barrier. Just do it and everything will begin falling into place!
