The second one consisted of 2 aptitude tests, one that was aiming for C/C++ and Linux knowledge, while the second one was going for IQ. The third interview was a brief one with HR and the future to be manager, where general stuff where discussed. Introductions, brief presentation of what Ixia, and the said department did.
