“The Best Support while Studying a Computer Science Degree”

“I’m a computer science student and regularly use Hackr.io to answer quick
questions I encounter in my coursework. It’s easy to find step-by-step guides,
tutorials, and examples for every programming language I work with.”

Inaya D.

“Hackr.io Made My Career Switch Seamless”

“I recently made a career switch from two wildly different industries — retail
sales to web development. Hackr.io grounded me and helped me find my way. I
learned about fantastic courses to jumpstart my switch, and the extensive
bootcamp reviews with pros and cons really helped me narrow down the most
relevant choices.”

Robbie M.

“Tech Interviews Are a Breeze with Hackr.io”

“I’ve been a web developer for two years, but I crave a more specialized role.
I’m preparing for job interviews with Hackr’s extensive interview question
articles. I’ve practiced mock interviews with Hackr.io’s data modeling interview
questions a few times now, and I feel so prepared.”

Aaynash J.

“Become a Better Programmer with Hands-on Resources”

“Hackr.io is a fantastic resource for diving DEEP into their programming
specialty. I work a lot with TypeScript, and always look for opportunities to
heighten my expertise. All you need to do is click the TypeScript (or any other
topic) tutorial page, and you’ll find a ton of options to practice with.”

Sharmin P.
