how do you know those queries are actually correct without domain knowledge?
Do you know enough about JOINs and how they work to be able to break those big queries down and figure out whether they are doing exactly what you're asking for in English?
Does your company actually look at resumes? you post in HN but nothing ever goes through. I have a feeling that your recruitment team is not doing their job properly (or being super selective)
I applied and got rejected without feedback. They stated that there was a high volume of strong applicants (if there were, why are they posting again?)
