Recruiter round: The recruiter might ask some basic, fundamental SQL questions.
1st round: 25 minutes for 4 SQL questions (easy). You need to be very fast and get to a solution very quickly. Communication wasn't the priority here.
Another 25 minutes for 2 programming questions. These are LeetCode easy to medium rated questions.
SQL: The first 2 questions require some aggregations. The later questions require joining.
Programming: Given a number, return the biggest odd number by rearranging its digits.
