MaxAB Backend Engineer interview questions

Very Quick HR Call to introduce me to the company and to schedule a technical interview, the interview was with their engineering manager and I think after it will be another HR interview to discuss salaries and so on. - The technical interview was so easy, some problem solving and SQL queries. - The questions was printed on a piece of paper, and he asked me to write the code on the paper ! - There is no data sample for the SQL queries at all. - The interviewer was already having an answer for one of the problem solving questions and want to see it and when I wrote my answer he told me that his solution is better, but when I traced his solutions it was wrong.
