I went through the interview process some 4 years ago. Perhaps things have changed. Every aspect very pleasant from airport check in to hotel accommodations, interview process. Even sat in business class in both directions. I was reimbursed for the travel taxes I had to pay when I checked in for my flight. The medical is no different than in China, Europe, or Indonesia or the Mid East. Standard Blood, Urine, EKG, TMT, Dental Exam, Chest X-ray, BP, EEG. I even got a kick of the ringing of the bell before entering the interview room.
I was offered the job, but after consideration of current pay and benefits and QOL, I decided to stary where I was at the time.
