We own our own fibre network end-to-end, from building to building. This means:

  • We don't depend on external partners for service quality
  • We deliver competitive pricing
  • We offer services globally, with consistency
  • We lead the way in innovation, free from restriction

With an open, inclusive work-space, we encourage all employees to be curious, to contribute to the culture and to challenge the status quo. Having this open dialogue is critical to our ability to generate new ideas as a team, which drives real growth.

The people in our business have always been one of our greatest assets, and as an organisation, we owe it to them to create a working environment where they can bring their whole selves to work. This means embedding Inclusion and Diversity into everything we do.

    Human Resources Graduate Interview

    Anonymous Interview Candidate

    Negative Experience
    Easy Interview


    I applied online. I interviewed at Colt Technology Services.


    The Interview lasted around 30 minutes. The lady was extremely nice and it went super well. I really had high hopes for this role. . I asked her who would be the ideal candidate for this role? And she said the person has to have a strong desire to learn and that’s about it. She told me I would know in 2 days. I never got an answer until I messaged her like twice. The day before the second interview I get an email saying that I wasn’t successful. I just don’t understand how can one be unsuccessful when this is a graduate scheme, I poured my heart and soul of how much I want to lear and be part of the HR department. I have the qualifications and studying for CIPD. I just feel like it wasn’t fair. Also, unprofessional not knowing until the day before.
