Workloads are generally ridiculous across the board. I have seen people who really loved the company and held their values pushed to the limit stress and workload wise, constantly requesting extra support who have subsequently left and replaced with multiple members of staff on extra money.
There is real limited room for growth. Senior hires will always be more attractive to this company. Promotions will also be given with delayed pay rises due to supposedly only doing pay increases in April...
Pay is well under market rates, the only way you will secure a good salary is to negotiate on the way in, otherwise it is very hard once you are in.
Toxic culture from the CEO is unfortunately very bad. This is fed down to Senior management, who have created an air of fear which wasn't apparent before. The CEO is quite happy to boast about firing people overnight, this has been a recurring issue of behaviour.
