Candidates should expect a progression that begins with an initial screening—often via phone or recorded video—followed by more in-depth technical or behavioral assessments. For certain programs, such as the Engineering Professional Programme, this may culminate in an assessment centre that includes group exercises, presentations, and multiple interviews.

The pace of the process can vary, and it is important to remain proactive throughout. The company emphasizes a collaborative, conversational approach, aiming to see if you will integrate well into their existing teams. Because some stages involve presentations or specific case studies, you should be prepared to invest time in researching the company’s business model and current initiatives.
