I received an email asking for scheduling a time for phone interview one week after I applied on their website. The phone interview only included behavioral questions and some other very basic question like "could you describe your research topic" or "why are you interested in this job." Also, the HR asked if I was ever applied other jobs in Mathworks before. After finishing the phone interview, my status on their website changed into "not ideal for this position". No idea where I did wrong.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
