Appen Associate Program Team Manager interview questions

Applied to the position online, and received an e-mail two and a half weeks later inviting me to an in-person interview with a panel of three Group Program Managers. Because they are a virtual company, the interview was held at a public space in a bookstore. The interview questions were pretty standard, but the most difficult part of the experience was that they could not tell me anything about the actual job because of the non-disclosure agreements they had signed. While I understand that their hands are tied in that respect, that made answering questions very difficult, and made me lose interest in the company and position.
