Saipem Junior Welding Engineer interview questions

First contact, by phone do it by the reruitment agency. We spoke about job offer, rotation, salary and at end the agent start speak with me in english. Next contact, by phone. I was announced I was selected for an interview face to face with employer. Face to face interview, was easy and I was very surprised about that, still with that I wasnt able to answer very clear at all technical questions. The reasons can be many, the true is I had a long time of waiting before and I was very tired. Always is better to be at interview fresh and also to check your base technical knowledge.
