Just awful. Interviewed for a position based in Singapore - interviewer did not have a firm grasp on English and his accent was extremely thick to the point of being nearly incomprehensible. Got irritated when I asked him to repeat himself or when I asked for clarification. Would regularly remark "let me make this easy for you" while asking questions that were definitely outside of the scope for an L1. Even got some information WRONG based on what I now understand having worked in the industry. Would recommend anyone interviewing here to exercise caution as it seemed like a rather toxic work environment.
