Pros
The work-life balance was superb, the team were great, the work was interesting and the stakeholders were demanding but fair. Overall the culture is strong - perhaps too strong at times, being inflexible in places - and, despite it being extremely challenging at times, it was an experience I will remember fondly for years to come.
Cons
The pressure on the business (not in the Communications world) was overwhelming for many and the regulatory strain is evident in some people's behaviour. The company is quite restricted (in terms of being able to grow at the rate it plans to) by the regulations in place and the DPA it operates under, and, while I was there, the turnover of employees in key roles made it difficult to have any kind of continuity to drive some of the large programmes. All of that said, if you want a good challenge, are willing to work hard to reap the rewards and have resilience, all of this will pale into insignificance.
