For the first round SQL interview, a few things to focus on (other than syntax and functional code) include: * Performance tuning and reasons for choosing your approach over alternative methods * Simplicity and readability (i.e. try not to overcomplicate your code) For the final round technical interviews, my experience was all scenario based questions which may include (but not limited to): SQL, Python (OOP), System Design (including fault tolerance, redundancy and scalability), Data Modelling, Performance Tuning.
