Entrevista
My interviewing for the position of Data Engineer was a 3-part process:
- HR
- Technical with the Line-Manager
- Hiring manager (Head of HR)
HR partners that interviewed me were pretty friendly. My Line Manager really knew his stuff, having a great conversation about projects I worked on and technologies. The Hiring Manager interview was testing my performance under pressure - so be prepared for that.
Overall a great experience.
