For these exercises, please use the tables you provided on the Google Form: people (user_id, people_name, user_type, username) group (group_id, group_name) people_group (user_id, group_id) 1.1 Please write a SQL query to get the usernames of all teachers. 1.2 Please write a SQL query to get the username of each teacher who belongs to any group. 1.3 Please write a SQL query to get the number of teachers who don’t belong to any group. 2.1 How about getting every user's percent difference of activity on the report date versus a week before the report date, for every date? Assume we have a daily user_summary table with every user's activity_level (integer) on every day. Don't worry about the exact date syntax. 3.1 If you want to measure whether new user registration rate (# of new users registered/all invitations sent out) for one design is higher than the other, What statistical test you will use?

I was provided a case study before the onsite interview and was asked to present through PPT during the onsite interview for 1 hour (including time for questions). The technical/analytical section includes SQL questions and a lot of statistical/modeling questions. R and Python questions were asked based on candidates' background. Behavioral questions were then covered in the next 2 sections.
