For first screening round many candidate appeared around 70 , and asked basic questions around python and sql. Like , use case of list , tuple, collision , classmethod, static method, shallow, deepcopy . Sql slightly on hard side for freshers , asked questions about window functions , partitioning sharding , clustered index and unclustered index

Interview is great. Focus more on basic SQL + problem solving in any language. Theory is a essential. It's a balance of both. You can focus on SQL + Basic Problem Solving + Some reasoning.
