How was the interview process? What was it like?

It was a weird situation, I was asked to prepare for a metrics & product sense interview and I got a theoretical ML interview with few practical aspects. The interviewer asked me intricate details about the algorithms. What is hinge loss in SVM? What is the slack variable? Why use quadratic function in MSE for linear regression instead of absolute value?

What technical questions were asked?

Modeling and ML Knowledge, ML Implementation/Engineering System Design, Python / Pandas, Business Case and Strategy, Product Metrics and Analytical, SQL / Analytics

What was one of your solutions?

Left Join: Joining a table on the left taking all of its records to a right table using a certain key, Inner Join: Joining a table on the left taking common records with the right table using a certain key
