Pros
Merged company is so much stronger than the two legacy organisations. It genuinely feels like the market leader and there are many hard working, talented and enterprising people at all levels of the business. It's a global business, so you can interact with people from around the world on a daily basis, and there are opportunities to relocate to many exciting locations. One of the company values is 'Innovative', and that does feel like a fair reflection of what the company tries to do.
Cons
The merger in January 2016 brought many opportunities and went pretty smoothly, but it has resulted in lots of changes to the business. Many people have left, and redundancies and restructures continue to take place which can result in feelings of instability. Redundancies and details of leavers are not well communicated, making the process feel a bit cloak and dagger. It feels like politics play a part in deciding who goes and who stays - if senior management take a dislike to someone, they may be forced out regardless of merit and ability. Salaries have been generally stagnant for several years, and bonuses remain non-existent - a symptom of the oil and gas downturn. Other benefits are average at best, and other forms of reward and recognition are inconsistently applied - a selection of 30 people or so get to go on a High Flyers trip, the hundreds of other employees receive very little.
