Pinterest Software Engineer (Data) interview questions

Initial phone screen with couple screening questions (how would you design a table?) followed by technical phone screen. They cancelled the phone screen 4h before the call and rescheduled the following day with a junior member of the team (<2 years of experience, looked them up on LinkedIn). Got asked two questions: SQL and Data manipulation using Pandas. They used hackerrank but told me I won't be able to execute SQL queries. Bummer. To my understanding, I got both questions right and the interviewer said so.
