" What I love the most about Callstack is that you have plenty of opportunities to evolve yourself. People here are really experts, and you can tell. There are innovative new roles you can join, chances to both share and learn, and real incentives to contribute back to the community. In just a few months, they made me feel super included. I found here not only experts in their jobs but also good friends."

" Joining Callstack, I was excited, mostly because of one thing - I was going to work with experts who built open-source tools that I've been using in my projects. Shortly after I started, I was asked if I wanted to be a part of a tech recruitment team. Not much longer, I was given a chance to host our podcast. Those were exactly the areas in which I didn't have experience but was fascinated with, and they gave me a try- isn't that awesome?! "
