Very informal, the director even swore in front of me. The way I got the interview was because of knowing somebody. It's very ad-hoc. Usually, you have 2 interviews - 1 with the director and 1 with the HR.

Their video recording interviews are useless and can't be used to check someone's ability to perform the task. I guess a newer process of interview should be introduced as this doesn't seem to be very useful for the candidates and the company.
