Pros

The role provided exposure to cross-functional work, HR and finance support. It helped strengthen my organisational, communication, and stakeholder management skills in a corporate environment.

Cons

My experience was significantly impacted by management practices within my team. I experienced what I perceived as unfair treatment and inconsistent communication, which affected my ability to perform confidently in my role. After raising concerns with HR, the situation did not improve in a meaningful or transparent way. There also appeared to be ongoing organisational instability, with restructuring and retrenchments creating uncertainty for employees.

Pros

People who’ve been working here for long time with the business are supportive and helpful but the current Executive Leadership does not care about the people-oriented culture.

Cons

Poor geo-expansion strategy and change communication. Regional office is not empowered for any decision making. Limited or no career progression in the regional office.
