Oracle Technical Support Engineer interview questions

Called by an HR for screening and after a week scheduled for a an interview on Hiring Manager and one of the team member. The interview lasted 30mins only. 15mins for technical interview and 15mins for situational questions. After the interview the manager informed me that he will transfer me to the hr for an offer.

Very basic maths question like Pythagoras theorem and basic SQL question using join and having and group by and other aggregate functions and they check the communication skills as well.
