Candidatei-me online. O processo levou 2 meses. Fui entrevistado pela National Instruments (Austin, TX) em ago. de 2012
Entrevista
I had one phone technical interview and four technical 1:1 personal interviews with Test Engineering staff. They all were very nice. Questions seem to start easy and get progressively harder.
