Pros

The lower level employees are mostly talented and a pleasure to work with, truly.

Cons

- CEO only speaks of cash flow and cares little about the ones who generate said cash flow - Salaries are intentionally kept as low as possible and raises (which are only given based on exceptional performance) are lower than the rate of inflation so you're actually losing money by staying here - Management is clueless, they just want to make the CEO happy and push blame on anyone else while having little to no involvement

Exceptional talent, weakened by leadership decisions.

Pros

Working remote was great. Being part of a team building software that supports cancer treatment was something I was genuinely proud of and honored to contribute to.

Cons

Upper and senior management frequently said one thing and did another. Communication was inconsistent across all levels, the goals and expectations were constantly shifting.

Predatory Company

Pros

Very few to list, terrible pay and zero accountability/assistance from upper management and directors.

Cons

Lowest pay in the country for the roles, company would much rather replace everyone with offshore contractors than actually provide value to their customers. They have one concern and that is the stakeholders. There is absolutely zero incentive for employees or future candidates to work with Mirion.
