OpenText U I Developer interview questions

Applied online, got email from Hr after a week or two,to confirm the F2F interview in EGL TECHPARK Bangalore on 16 July 2025. I called the HR and asked that this positis for UI only or full stack, he replied 90 % hi and 10% back end . I was ok for it, but when interview started they asking questions on db, Java, Angular ( I have only react experience) I said I do not know these. Bad experience
