Infinite Roots interview questions

Almost 2 weeks after applying, I got an interview invitation by email. The interview was done with 4 persons, 2 related to HR department and the other 2 to the technical department which the position belongs to. Everyone was very friendly and easy-going. The questions were the usual interview questions. The HR interviewers were just having a get-to-know me conversation were we talked about myself a bit, my hobbies, and I in turn asked some questions. The technical interviewers got more in depth into my work experience and questions related to the job. There were some repetitive questions about whether or not I know how to do a skill, and it did not feel good to be asked more than twice about a skill I had already made clear the first time that I know of but haven't worked with before.
