I applied online using their website. Within a week I got a call from the HR for the interview. Total 5 remote interviews happen. The first interview was on the basics of ML and my past projects. The interviewer was an ML scientist. The second interview was on programming, he asked two problems and said me to discuss the solution before you start writing. The interviewer was the director of AI in Singapore office. The third and fourth interviews were once again on the basics of ML. The interviewers are the president and the chief data scientist of the company. Finally, the fifth interview was with CEO, he asked behavioral questions. Overall the process took more than two months and still waiting for the results.
