Pros
You will rapidly learn that you deserve better from an employer. The company turnover rate means you will very quickly establish a network of contacts in other companies across the sector.
Cons
It's not so much that the company is a rudderless ship, rather that the Directors seem intent on wilfully steering the ship towards every rock, reef, and jagged coastline in sight. Rudderless would be an improvement. The staff consists almost exclusively of an ever-changing roster of either fresh graduates, or others trying to break into the industry. The company then frequently tenders for work which their employees lack the experience and expertise to deliver effectively. Consequently, they company seems to be in a perpetual state of either an existing project disaster, or heading towards the next one. The Directors take zero accountability for their decisions, actions, or for their company as a whole. They respond to the chaos they create by leaving their undervalued staff rescue every situation without any support. Sadly, the Directors never walk so far away as to risk losing the ability to fire abuse, blame, and criticism at their employees at every opportunity. The concept of a 'no-blame culture' only extends to the Directors themselves - everyone else is very much in the firing line. This would be bad enough if expectations were in anyway reasonable or sensible, but they rarely are. Instead, you'll spend a disproportionate amount of your time pandering to the Directors' narcissism and egotism, or suffering their astounding ignorance. All of this results in an average staff retention period most appropriately measured in days, weeks, or months... but certainly not years. Save yourself the trauma and look elsewhere. What you stand to gain from OSC will not be worth the cost.
