All the questions are from the question bank. It was a very pleasant experience. The interviewer was very nice and even helped me to answer a few questions. I am awaiting the call to Natick.

I have jotted down a few of the questions:

JAVA

• Difference between final, finally, and finalize
• Exit condition for the Fibonacci series
• OOP

Math

• Find the inverse of a 3x3 matrix.
• Find the orthogonal vector to A = i + 2j + k; B = j + 2k
• Find acceleration from velocity

DSP

• Difference between discreet and continuous delta function
• FIR vs. IIR
• DFT vs. FFT
• The sampling frequency for 3cos(600pit) + 2cos(1800pit)

Matlab

• Difference between A.' and A'
