McMaster-Carr Recruiting interview questions

Was reached out to by a recruiter on LinkedIn for an interview for the position. We went through 3 phone calls that were all very positive and informational. Ultimately, about 30 minutes after the last phone call I was sent an email saying they were moving onto other candidates with no other explanation. A bit off putting since all the conversations seemed to go professionally and well. Even though IL is an "at will" state and explanations aren't needed, it's not a great way to go about the process all the same.

Initially the person I spoke to was really nice then she became very rude--for no apparent reason. She was very snobby. One really pathetic question she asked was, "How long were you in college." --despite my resume clearly stating the dates and that I received an advanced degree. Don't waste your time interviewing with them.
