First, I would really like to mention that the entire process was really quick. Compared to any companies I have applied so far, none of them ever came close. The whole process was finished in only about 2 weeks. Also, most of the interviewers were both friendly and approachable, which really helped a lot to calm myself down and loosen up. Of course, they asked questions that are straight to the point but they also talk about other things that are not related to the job application, which greatly lessens the tension.
In summary, it was pretty great! The only thing that bothered me though was the number of interviews I've had (5 interviews!), which was also a first time experience.
