Entrevista
Overall a lengthy and difficult process. Lots of Leadership Principles involved, so practice them very very well. Leetcode Hard SQLs will do the job. The recruiters prepare as best as they can, but Data Engineering interviews are till not explicitly out there in terms of prep materials. Most of my interviews went absolutely technical in-depth with my experience and projects.
Got a phone call from the recruiter and was excited. Only to know that they were not moving on. The role was for L5
