Behavioral Technical Case

After applying, I went through three interview rounds within two weeks, with about a week separating each. A consultant was my first interviewer, then the hiring manager, and finally a director for the last one. The interviews were tough, covering supply chain planning, analytics, and digital transformation, and mostly focused on my past experience, technical abilities, and solving case studies.

Confirmed questions2 questions
