Pros

Flexible work arrangement (2 days in office) & supportive colleagues, many of whom have since moved on

Cons

The company culture has changed noticeably over time, particularly following shifts in global senior leadership and operating style. Communication and transparency could be improved, and at times the environment can feel more pressure-driven and blaming rather than collaborative. There is also a perception that alignment is sometimes valued more than constructive feedback, even though healthy debate can ultimately benefit customers and the company. There have been multiple rounds of layoffs, and a number of experienced colleagues have left the organisation. In some cases, employees felt there was limited visibility into how decisions were made, which has affected morale. Some teams feel less confident about the long-term direction of the organization.

Pros

Nice company to work for only if you are lucky

Cons

I face bullying almost everyday from my manager. Complaints about bullying to senior management goes into deaf ears because of his influential contacts with executive level people and rubs shoulders with top execs
