Pros
None, or maybe the ability to share awful stories with other ex-employees of Topsort, of which there are a large number.
Cons
The business is led by management that have no clue how to interact with human beings. Much like all the other 1* reviews claim the culture is toxic. There is daily anger shown to staff, bullying behaviours, extreme micro management, false accusations, basically every toxic trait that could happen in the workplace happens here. What makes this worse is this happens in group meetings and slack channegls. The staff turnover is extreme with the average employment being months, highlighted by the number of the product and tech team who have left in the last few weeks. Clients are not notified of these changes as the management know how badly it would reflect in their business. Avoid working here at all costs. Also the fact that Glassdoor has confirmed that Topsort is falsifying their 5* reviews and now has a warning is pretty damning.
