Koch interview questions

I was told it was not going to be a technical interview. First question was a Java technical question about counting characters in a string. I said how to do it but the interviewer said he wanted a tuple. I never heard anything from them after the interview.

too many vague and irrelevant questions about your correct company and position. less about applied position. the interviewers are not professional or have less knowledge about the subject. They forgot to follow up after the interview. after 3 weeks and sending several emails I got a short response
