Pros
Salaries are well above market rates as they cannot attract or retain staff. Long term employment option if you are incompetent and don't challenge the managements thinking.
Cons
Ohh so many! Executive Leadership fill their days with backstabbing power plays with each other using staff as pawns. Forging emails, lying, backstabbing, firing people to suit your games....all in a days work for the management. Staff are treated as things to be abused, with screaming and physical abuse the norm from both male and female managers. Anyone who tries to improve the place will be initially welcomed, about 6 months in the old timers will start working against you for rocking the boat and showing up their incompetence; at the 12-18 month mark you will be pulled into HR and fired, often with no reason. Some managers have 20+ workplace bullying complaints against them and are still promoted. Their job ads talk about solving the world most challenging problems and technologies such as hybrid cloud, blockchain, data analytics, machine learning etc. The reality is they maintain some legacy desktops and servers; they do nothing in these areas and the CEO, ELT and middle managers are vehemently against any new approaches. Working here, if you are competent, you will be bullied, screamed at and physically assaulted; whilst working on technology that is ancient and with customers (all two of them) that have had enough.
