Technical Coding
The first round was a technical interview. The interviewer asked for details about my projects and then posed a SQL question. However, when I explained my solution, the interviewer seemed confused, as if unsure of their own question. It seems important that interviewers are prepared with datasets and clear expectations for results. I ended up creating a dataset to illustrate what they were looking for.
