" 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."
"Working at Callstack has been a game-changer for me. I’ve grown alongside experts, boosting my experience and making great connections. I love taking on different challenges that help me learn and contribute my skills to various projects. The atmosphere is open, friendly, and full of innovation. I truly enjoy multiple networking events such as Workation. It’s a place where respect and new ideas really matter."
" 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?! "
" When I started with Callstack, it was the perfect opportunity for me to grow and improve my IT PM skills in a very specialized Techstack, working with the top Experts in RN. This opportunity evolved into a chance to hone my PM expertise and grow my sales competencies by making a lateral move into the Sales team. I work with the biggest clients in Healthcare, Fintech, and Automotive, providing them with world-class solutions and having fun while doing it! "
" What I value the most at Callstack is the possibility of developing within a mentoring program, which gives me a chance to learn from the best Experts.Whenever needed, I can get help not only from my closest team members. A big thing is that there are also a lot of girls who code at Callstack! Of course, remote work conditions are also a big plus. And big parties. The spirit in the company overall is just amazing! "
" During my time at Callstack, I’ve advanced as an HR professional and discovered a supportive community that values employee well-being and development. Company activities bring us closer and make us feel like a tight-knit family. This sense of connection has enhanced my professional growth and forged enduring bonds that make Callstack exceptional. Callstack isn’t just a workplace; it’s a place where personal and professional growth thrive. "
" The easiest thing to say about the company is a great atmosphere. But at Callstack, I mean making the most of it! My workmates became my friends and training buddies. Our parties always feel like a top summer festival, and our office feels like home. On top of that, the possibility of changing projects and getting to know new tools makes working at Callstack a complete path that I want to follow for a long time! "
