Grubhub Data Scientist interview questions

I was scheduled to have zoom interview with the hiring manager but on the interview different person showed up. The interviewer looked really uncomfortable and shocked when she saw me. I am not sure the reason but my assumption is that she didn't expect to interview a black person with a braids. I never felt this awkward or uneasy talking to someone before. The interview questions was all over the place and didn't feel like the interviewer knew what she was asking or if the answer I was giving her was the right one.

This is the type of interview where after doing the HR screening and meeting with the lead data scientists they have you do a 72-hour take-home analysis where after submission they give you no feedback or discussion on your work. Completely unprofessional . Don't waste your time.
