ABOUT THE INTERNSHIP
Step into the future of technology by joining LITIT through a 2 months unpaid internship designed to elevate your skills and career.
In the real world battles of AI vs Juniors for positions you’re invited to a boot camp, to train under supervision of seniors. We will not give you bean bags to sit on and drink your lattes, we will not distract you with latest Xbox Series X games or corporate mindfulness sessions, you will not do yoga at the company’s expense. Left already? Or keep going…
We will give you broken builds in CI/CD pipeline, unclear requirements, running production code written in 2009, and a production issue at 16:57 on Friday. We will give you trenches in survival mode, we will give you courage to stay, to defend yourself by learning.
You will learn how to read logs before asking questions that can be google’d or claude’d. You will learn why “it works on my machine” is not a solution. Even “it works in my container” isn’t one either. You will learn that documentation is sometimes wrong, tests sometimes lie, and the environment you prepared for the customer can go offline just five minutes before the release demo. You will learn to brush it off while your shirt sticks to you with cold sweat.
You will sit next to people who have seen systems fail in spectacular ways, lived to commit the fix, and tell the story.
They will not flatter you. They will review your code and scrutinize it, ask why you wrote it that way, and then ask again.
If you survive the first month, you will understand what junior developers used to learn in their first two years on the job
before AI started writing half the boilerplate. You will get scars, but they will be your own earned scars, the kind you can be proud of.
AI vibe coders will envy these experiences. At the end of the day, you are not what you eat, but what you survived through.
If you don’t last a week, at least you’ll know your weakness and relaxed attitude led you to a crumbling end.
Time to renew your Cursor subscription and level up your prompting - again, and again, and again. Apparently, that works for some.
So… still with us? Read on. This is not a startup playground to boost your ego. It’s about your future and your place in it. Ready?
This genuinely unique opportunity lets you collaborate with a prestigious global client, work closely with senior industry professionals, gaining invaluable hands-on experience.
