How much database knowledge should I have for an entry level DS job/internship?

I’m currently entering my 4th year in college and am a bit stressed due to the amount of things I need to learn before applying for a new-grad job. I currently am taking a SQL course on Udemy, and I was wondering if it would be enough to only know SQL and be able to pass interviews involving SQL queries, or if I need to have more in-depth knowledge such as Database design, and knowing the differences between sql/nosql, etc
