Just not worth it - Anonymous employee Quantium Employee Review

The working hours are obscene. Anything less than a 12 hour working day was highly unusual, and 16 hours+ not uncommon. This is exacerbated by the fact that the remote working options were pretty poor, particularly for such a technological company (there was a VPN, but the connection was very slow and laggy, to the point where it was almost useless). They're not very strong on people management, but are aware of this and trying to improve - there are lots of inexperienced managers.
