Crate and Barrel interview questions

They send 3 technical question via email how do you explain test cases w/out coding from here probably you will move to next step. I don't know anything about interview process

The interview was one of the worse experiences I have ever had. I only had 1 interview with an Recruiter and she was one of the worse recruiters I’ve ever interviewed with. The interview only lasted 9 mins. She first started off with what she does for the company, then asked me 3 questions. During the third question she cut me off and ended the interview. I did ask her one question about the job and said its self explanatory in the description. I should have asked why she cut me off like that, but I was still trying to be professional and not rude like her. Based on this interview alone I’m glad I didn’t seek anything further with the company or be asked too and will always remember this experience with this company.
