What to expect after you've applied
After your application is reviewed positively by the hiring team, the interview process for applied scientist roles at Zalando typically consists of several steps, depending on the seniority level:
- Initial call with a Talent Acquisition Partner,
- Interview with the hiring manager or a preliminary technical screening, or in some cases, both
- Final Interviews (typically between 4-5 interviews covering different focus areas)
- Live Coding interview
- System Design / ML engineering interview
