Databricks Solutions Architect interview questions

Spent 40 hours completing their take home assignment for them to tell me they're not moving forward, not even offering a 'grade' on the assignment. Poor interview experience, not much empathy from the recruiters.

The interview process was as below: HR Phone Screen (Role and Logistics) Technical Interview (Data Science, Data Engineering) Coding Assignment (SQL queries, Spark optimization, Machine Learning) Technical Interview (Architecture Whiteboarding) Super Day (4 Interviews + 1 hr Technical Presentation)
