They Only interested to Spining Section, I am telling My area of interest is weaving. They ask very few questions about weaving when they ask very specific questions from specific like asking the particular value of draft of a specific count that wasn't expected. The technical head told me dumbed as I can't answer what they expected it is truely unprofessional and inappropriate for any interviewer, especially in a technical role, to call a student or candidate "dumb" for not answering a question as expected. Interviews are meant to assess knowledge, skills, and potential, but they should also be respectful and encouraging.
