Radware Student Backend Engineer interview questions

Stage 1: Short phone interview with a recruiter who ask few questions about my availability, university background and my salary expectations(they tend to offer 80-90 NIS per hour). Stage 2: I was invited to on-site 1:1 interview with a team leader who asked me several technical questions. The interviewer was very nice and friendly and the atmosphere over the interview was pleasent. Stage 3: After I passed the first interview I was invited to on-site 2:1 interview with two engineers. They both were very nice and friendly. I was asked two design-based questions. Stage 4: The final stage is a HR interview, but I received an offer from other company so I ended the process earlier that interview. The engineers and the team leader were very friendly and the interviews conducted in pleasent atmosphere but the place feels like old-fashion workplace and not like a tempting HiTech company, in my opinion at least.
