Dathena Senior Data Scientist/Computer Vision Engineer (Bangkok) interview questions

Initially, I have been asked if I'm okay to work in Bangkok through the mail. Then The initial screening round with their Chief Science Officer through Skype Video Call. The Chief Science Officer told that there will be a coding assignment but she never sent one. She asked very basic questions. As a matter of fact, they are only looking for free advice and ideas to tackle their problems in OCR. When I asked them for the result, she did not respond for almost two weeks. They are too unprofessional to leave all applicants to be hanging for the response. She responded after one and half months!
