I spoke to Mathworks at my university career fair and got selected for phone interview. Pre-screening interview questions required objective or single sentence response. I choose signal processing and most of the questions were same as those found glassdoor threads. Got selected for on-site. Problems were given from signal processing and coding topics for technical round, followed by manger and HR.

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.
