The interview process was pretty good up until the final FOUR HOUR 'on-site' which included technical components and lots of scenario discussion. One interview expected you to write a rhetorical SQL code with a schema outline but no actual IDE to write or execute the SQL.

It was streamlined and clear. Got to onsite. For the technical onsite The interviewers were somewhat unprepared for the cases and the emphasis was on how on the fly you can write code which I think is a very strange criterion for a role that needs time and experimentation ... it was rushed and disorganised. The nontechnical was just based on churn analysis. Based on my feedback I did a great job on the technical part. I was lacking in the other part so shouldn't comment on that.

Question 1
Technical: fast coding round they expect you to clean and model data in 50 min. Non-tech: churn analysis
