    As someone early in my career, working at C3 has been a great experience. I am working with people who are highly intelligent, motivated and eager to make an impact. Management encourages me to voice my interests and dictate the projects I would like to be involved with while providing resources and support to help me succeed. The culture is professional, hard-working and friendly. Everyone is very excited for the future of the company. I truly feel like I am a part of something special.

    Difficult Interview


    I have recently started working at C3 IoT. Even from the interview process I could say that the group I was going to join included some of the brightest people I have met during my career (and I have been around). The process was extremely smooth and engaging. Starting with some entry interview tasks and questions, I had interviews with several members of the team that work within different projects in different areas. During this process it was clear that I was being evaluated not only based on my knowledge in specific areas, but also based on my ability to learn and grasp new concepts that could potentially be useful for the company now or in a future stage. I have to say now that I have started at C3 IoT, I can see the logic behind the interview process as the company is involved in different areas and constantly increasing its scope.
