Susquehanna International Group Network Engineer Interview Questions
& Process

The interview covered basic CCNA level topics, including optics and Layer 2 packet flow. There were also scenario-based questions focused on network designing. I didn't get the offer because I lacked knowledge about the physical connection of devices and fiber optics.

I applied online with SIG and then reached out to the recruiter on LinkedIn. She called me the next day. The first round was a mix of technical and behavioral questions. I got contacted by the recruiter within a week for the next round, and she was flexible with scheduling. The second round was a phone interview with two people from the networking team, focusing on cabling, routing, and switching. After about 10 days, the recruiter contacted me for the final onsite interview in Bala Cynwyd. They provided train tickets and reimbursed travel expenses. At the onsite, I met the recruiter and then had the first round with networking engineers asking about L3 switches, STP, subnetting, and redundancies. The next round was with two IT managers where I was asked to design a network and discuss redundancies. I didn't do well on these because I lacked in-depth knowledge of L3 switches and redundancies. The third round with the IT director was canceled. After the interviews, the recruiter gave me an office tour and arranged my ride back. I received a rejection email within 4 days, which I expected. Overall, it's a good company with challenging interviews requiring CCNP R&S knowledge, which seemed high for an entry-level role.

Since I'm applying from out of state, they might offer an onsite interview sooner. My interview process started with a 30-minute initial call with the recruiter. Then, I had a 1-hour technical phone interview with team members, followed by a 1-hour phone interview with the team manager. There was a scheduling mix-up, and one interviewer was over 30 minutes late, so we had to split that interview into two 30-minute sessions due to my availability. After passing these phone interviews, I was invited for an onsite interview, which ended up being much longer than advertised. I was told it would take 2-4 hours, but it actually lasted 5.5 hours, which really threw off my schedule. I'd planned based on the maximum of 4 hours plus a 30-minute buffer, so an extra hour and a half was quite inconvenient. Honestly, I almost walked out, but I felt the interviews were going well and didn't want to risk missing out on a potential offer. The onsite included two technical interviews with team members (two interviewers in each), an interview with the team lead and another manager, a meeting with HR to discuss benefits, and a final meeting with the IT division manager. Overall, I was really disappointed with how the entire interview process, both phone and onsite, was handled. I felt they didn't respect my time, and sometimes they asked questions that were irrelevant to the role or presented incorrect information as fact, expecting me to correct it. I didn't get an offer; the recruiter sent a generic email saying they were impressed but moving forward with other candidates. I asked for feedback, but never heard back.
