What a coincidence! I've got my dream job too!

The things I did to get here are honestly kind of stupid. I started out at a defense contractor after graduating and left in the first six months because all the software devs were jumping ship. Went to a small business defense contractor (yep that's a thing) and learned to build web apps with React and Django. Then the pace of business slowed so after about 18 months I got on the Leetcode grind and got into a FAANG. Realized I hated it, so I quit after about 9 months with no job lined up.

While unemployed I convinced myself I was going to get a job in robotics (I actually got pretty close, I had 3 final level interviews with robotics companies), but the job market went to shit pretty much the exact day I quit my job lol. I spent about 6 months just learning ROS, Inverse Kinematics, math for robotics, gradient descent and optimization, localization, path planning, mapping etc. I taught at a game development summer camp for a month and a half, that was awesome. Working with kids is always a blast. Also learned Rust and built a prototype for a multiplayer browser-based coding game I had been thinking about for a while. It was an excuse to make a full stack application with some fun infrastructure stuff.

The backend is no longer running, but originally users could see their territory on the galaxy grow as their code won battles for them.

For the current role, I really just got lucky. The previous engineer was on his way out for non-job related reasons. He had read a lot of the books I had (Code Complete, Domain Driven Design) and I think we just connected over shared interests and intellectual curiosity.

I think that in the modern day, so many people are really just in this space for the paycheck-- and that's okay! Everyone needs to make a living. But I think that if you have that intellectual curiosity and like making stuff, people will see that and get excited. It ends up being a blessing and a curse.

I have failed interviews because of honesty "I would Google the names of books and read up on that subject" or "I think if I was doing CSS then I would be in the wrong role" (I realize how douchey that sounds but I just was not meant to design things, I have tried). But I have also gone further in interviews than I should have because I was really engrossed in a particular problem like path planning or inverse kinematics and I was able to talk about things in plain terms.

I think it's easier to learn things quickly if they are something you're actually interested in, it becomes effortless. Basically I just try to do that so I can learn optimally, then I try to get lucky.

EDIT: Oh I just thought of more good advice. Find senior devs to learn from. They can be kind of grumpy in their online presence, but they help you avoid so many tar pits. I am in a Discord channel with a handful of senior engineers. The best way to get feedback is to naively say "I'm going to do X", they will immediately let you know why X is a bad idea. A lot of their advice boils down to KISS and use languages with strong typing.
