Received an e-mail one day after application asking to make an online test. Since I selected C++ as the language with which I feel more comfortable, the test consisted on few C++ hard questions, it was not an IQ test as I expected. Got Proficient level (3.23/5) at the test, about 25-30 questions and 3 minutes to answer each. Reading from other reviewers, I think they only contact you for the in-house interview when you get Proficient Level of Advanced (from 3.50 to 5), which seems to be the second filter after skill assessment. Next working day received an e-mail informing of refusal (good to know, anyway).
