First thing- In order to work for this position, you need to know Matlab and must have used it for some period of time. Technical phone screening had three sections- 1. Programming language of your choice. 2. Real Time OS concepts. 3. Basic Matlab questions.(yes, basic..a little too basic) Java was my preferred language. Questions were fairly straightforward like- 1. Explain Classpath in Java, 2. Explain Garbage Collector mechanism 3. Difference between == and equal() and which one should be used when. 4. A situation when the finally block wont be executed in Exception handling. Ans- exit() and some other simple questions already discussed here. RealTime OS- 1. Inversion Priority- Definition, example, How to avoid ? 2. Deadlock 3. Difference between RTOS and OS and some more basics MATLAB - I was not able to answer most of the questions, I rarely use Matlab beyond drawing plots and graphs. But most of them were basic. Duration- 45 mins.

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.
