    I have been working at C3 IoT full-time (Less than a year)


    I have worked with many companies in the past, not only as an employee but also as management consult. C3 IoT is by far the best I can ever imagine. Here is a list of reason why I come to work happily everyday:
    - Legendary founder/CEO Tom Siebel with great vision for the company: He has over 40yrs of experience in Information Technology and has founded Siebel system and led it through tremendous growth and IPO. He knows how to lead a company through various phases as a startup and eventually a public company. A billionaire who has earned more than enough to retire years ago, Tom has put his personal wealth and continuous hard work to this 8 year old company with his passion to again create something revolutionary. He also brought in many experienced leaders and advisors to the business.
    - Experienced high performing leadership: Many of the top leaders are experienced ex-Oracle/Siebel System veterans and ex-McKinsey consultants. They are down to earth, practical and exceptionally intelligent with great executions.
    - Talented young engineers & data scientist: C3 has a lot of young talented engineers and data scientists (with PhD degrees) from top universities not only in U.S. but around the globe
    - A unique product with tremendous value proposition: C3 IoT offers a next generation machine learning/AI software platform for the enterprise. This is a unique new category that C3 basically has no competitors in. The business value provided to the large enterprises by having the capability to predict the equipment failure, optimize inventory and detect fraud (and many more) is significant beyond the cost of the software application/platform
    - Silicon Valley culture: With the Silicon Valley genes, C3 IoT encourages continuous learning. Employees will be rewarded after completing Machine Learning/Deep Learning coursera classes. Reading of books in the field of ML/AI is also encouraged.
    - Refreshing office environment: The first time I stepped into the C3 office for interview, I immediately fell in love with the vast space and oxygen tank type of workpod space surrounded by plants. High quality lunch and snacks/beverages are provided. Beanbags/couches scattered around the office. Pingpong and pool table available. Friday happy hour with pizza, beer and wine.

    In summary, C3 IoT has a rare combination for a startup/pre-IPO company of visionary leader, experienced leadership and talented young engineers. It also has the culture and office environment you will love to be immersed in.

    I am indeed proud of being part of this fast growing company. The company and people around me, constitutes more than 70% of my happiness in life now :)


    C3 IoT has a high performing culture with transparency. High performance is rewarded but below the bar behavior is not tolerated.

    Advice to Management

    Continue to lead with vision and superior execution. And attract high caliber talent to our great company.

    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.
