For the last stage of the technical interview, they came with general machine learning questions plus some coding. However, the team was not very prepared and I am not pretty sure if they are really looking to hire someone. One of the interviewees was playing with her phone over the near two hours interview and sometimes came with a question which I already replied. she had a heavy accent and she was not well prepared for the interview while she was confused in coding and couldn't transfer what she really wanted. I believe they need to have more professional ones when interviewing skilled candidate.
