Ask HN: How can I start preparing for interviews? And how to stay motivated

I want to switch to a Software Enginnering role (I joined my current company as a quality engineer last year) because I think it aligns more with my career goals.

I've tried to start preparation for LeetCode styled interviews but I always end up abandoning it (mostly due to lack of motivation). Maybe I just don't enjoy it as much as creating other stuff.

I do want to move forward in my career and I do understand that I have to prepare for interviews.

Can anyone share share their journey of preparation for interviews, sources, sources of motivation, tips, etc.
