DHL Express Data Scientist interview questions

Only interviewer is the hiring manager, asked to rank basic data science skills such python proficiency on a scale from 1 to 10, without explaining or supporting with past experience. Soon after they sent the rejection email. Duration is 10minutes and interviewer was late by 15 to 20 minutes. There was no opportunity to 'fail' the interview with such a format but they sent me the rejection email soon after. So clearly they had something in mind.
