Explain all types of joins in SQL (using whiteboard, with examples). Having OrgTable(guid,name,office_loc,headcount,org_guid) given org_guid has 1-M relationship with guid, write a query to return team_guid,team_name,org_name,org_guid (to show which org each team belongs to) by leveraging a CTE (Common Table value Expression) recursive query.

Use the STAR Methodology: Structure your responses using the STAR approach (Situation, Task, Action, Result). This helps in providing comprehensive answers and demonstrating your problem-solving process effectively. Engage with the Interviewer: Ask clarifying questions to ensure you understand the context and specifics of what is being asked. This shows your engagement and helps tailor your answers more accurately. After answering, check in with the interviewer by asking if they need further clarification or if they understood your response. This ensures your answers are clear and addresses any follow-up questions they might have.
