Mirum interview questions

Unprofessional. Got contacted by hr 5 weeks after job application. Direct interview call with project manager. No respect for candidate as he didn’t put on camera while I was talking to the air. Interview was conducted in Cantonese only, casual conversation but far from professional. The manager shows high demand, sounds like he’s looking for a worker who follows and obeys strictly. Said they will update in one week progress. but nothing was heard back after this interview.
