I applied and got interviews multiple times. Some interviews could be a bit weird cuz interview officers sometimes asked unrelated questions as if he/she's not sure what position I'm applying for. I guess what's happening is that they hire too casually. Their average tenure is 0.8 years according to linkedIn statistics, which basically means that people are leaving all the time and they need to hire all the year round. This might explain why I sometimes feel that their HR made calls to unmatched applicants. As for the interviews, I don't think that they explained clearly about the jobs in the descriptions, and I don't think that some of the interviews were well-arranged.

Hard, ask a lot of soft ware design questions not directly relating to Machine learning, But interviewers are friendly and nice. You need to prepare a ppt as well, introduce your project, They also asked a code question to be finished with out copilate. All work must be on site as well.
