    I have been working at C3 IoT full-time (More than 5 years)


    I enjoy the challenges posed by the problems we're solving. Little of the work has been easy, but the successes are gratifying. I appreciate that employee contributions are rewarded in ways that are apparent every day. I've learned a lot. The people at the company inspire me. Sometimes they make me laugh. Everyone pushes hard to deliver comprehensive solutions to customers and to each other.


    Working at C3 IoT can be daunting at times, but it is worth it. You will be rewarded.

    Talent Acquisition Coordinator Interview

    Anonymous Interview Candidate in Redwood City, CA
    No Offer
    Negative Experience
    Average Interview


    I applied online. The process took 2 weeks. I interviewed at C3 IoT (Redwood City, CA).


    Applied online and then was contacted by their external hiring manager. Did a simple phone screen with a higher up who invited me onsite for an interview. Onsite the process was disorganized. Just a few notes:

    1. No one instructed me on how to enter their suite. A random employee let me in and the external hiring manager alluded to confusion regarding my entrance.
    2. We had to search for an open meeting room as one wasn't booked for an interview. The table in our meeting room was covered in papers and empty water bottles.
    3. It became quite apparent that the more administrative roles can expect this to be typical treatment, as I was told multiple times throughout the interview process incoming engineers should expect A+ treatment.
    4. Standard interview process, but a strong emphasis on hiring "smart people". I took this to mean hiring men from Stanford and UC Berkeley, as the two engineers I interviewed with used male pronouns exclusively and name dropped Stanford and Berkeley.
    5. During the interview, I was handed two other job descriptions for jobs I may be interested in. I took that as a hint I wasn't getting the job I was currently interviewing for.

    They did come off as a new and upcoming company that could benefit from a stronger administrative/human resources presence. I unfortunately do not think that is their emphasis. They would benefit from taking a look at their interview process for roles outside of the engineering realm.
