I was previously building my own startup straight out of college after graduating (Grad 2018). We built an iOS and Android app for aggregating college events on a single platform. We worked on it for close to a year. The product got very few users. We figured that the problem we were trying to solve did not exist in the first place. I lost everything I had saved by doing contract work during college. I'm penniless now.

The next few months, I will be dedicating full-time to prepare for tech job interviews.

I'm learning React and Nodejs on the side and enjoy working on projects to hone my skills. I feel I need to keep coding otherwise I'll lose my skills.

Should I devote 100% of my time to refresh my Algo & DS and leetcode?

Or is it ok if I spend like 40% of my time developing projects and 60% on leetcode Algo/DS?

I have around 2-3 months. How should I best utilize this time?
