Total 4 rounds - 1 general interview, 2 technical interviews and finally 1 technical presentation. The whole interview process took 2 months - a very long process. They did not want to introduce the projects they doing, not even the slightest information, giving excuse that they are all secrets. All rounds were easy except the technical presentation which took half an hour presenting followed by 25 minutes of intense interrogation-styled Q and A by around 7 people. This is what I felt: It is a waste of time because they do not have any intentions to hire. They just want free information and free knowledge from you in the technical presentation. They just find lame excuses to rule you out during interrogation-styled Q and A. They also did not read your resume beforehand because in the final technical presentation, they asked the very basic information in which I already stated in my resume. This is not acceptable since there were already 3 rounds held before the final technical presentation round. If they sincerely want to hire, then it would not have taken 2 months for the whole interview process. The team is very authoritative and dictating, not a good sign. So far there are no good AI products produced by the company, just go to their stores and you can find out. My advices to candidates: Do not apply for AI or machine learning jobs, you will get upset spending days and days preparing your technical presentation to perfection but only to find out they just want free information and knowledge from you. My advices to company: No advices to you because you know what you doing.
