Saipem Graduate Engineer interview questions

After applying online, received a call from the internal recruitment consultant inviting me for an interview for the coming days. The process was well managed in this part with a date being agreed and immediately they booked and paid for flights for the interview. the interview itself was very short, disconcertingly so and then a job offer was made the next day to me. I think that, although it is sometimes good for the employee, the interview process should be more thorough.
