Applied for the job through linked in and received a call one week later setting up the time of interview. I met the HR first and she looked unprepared and so the CTO does. The interview was technical mainly, and he asked about tech stacks and some fail scenarios and promised he will send an assignment, but later i lost the interest and didn't proceeed when i saw the reviews in Glassdoor and heard some not helpful stories from the tech community in HK.
