Got contacted by HR, who introduced me to this opportunity. I decided to apply through a form on their website.

There were 5 stages:

1. CV screening

2. HR phone interview: very professional and easy-going interviewer, very nice to chat with. She asked about my CV, studying, and experience. Then we talked about my interests and attitude - I had to make real-life examples of previous experience to prove I was being honest.

3. Skype interview with System Engineer: Again, a good experience, a professional and easy-to-talk-to person. He asked about my academic career, with insight questions on my exams + 2 "technical" questions about networking.

4. Skype Manager Interview: toughest, in my opinion. Very specific questions - which required very specific answers - about life experience to test my attitude and approach to working/life stressful situations. Anyway, he was again professional and kind. He asked 2 technical questions about networking, too.

5. Final Manager (the one you will work with if he/she agrees to hire you) + Job offer Skype call: More a call than an interview, asked questions about why I wanted to join them and more in general what I am expecting from such an experience.

Questions weren't too technical nor difficult, you just need to review basic telecommunications and networking concepts.

What is the difference between Layer 3 and Layer 4 in the OSI model?
