      Network Security Engineer Interview

      Jul 13, 2020
      Anonymous Interview Candidate
      Bad Homburg v. d. Höhe
      Declined offer
      No offer
      Negative experience
      Average interview

      Application

      I applied through a recruiter. The process took 2 months. I interviewed at NTT DATA (Prague) in May 2025

      Interview

      The interview process was quite brief. While the team was generally friendly and welcoming, the questions were almost entirely based on rote memorization of Fortinet Firewall specifics. For example, instead of asking about the general operation of NAT (Network Address Translation), they focused on device-specific queries like "How do you configure NAT on a Fortinet firewall?" The emphasis was clearly on vendor-specific knowledge rather than underlying networking principles.

      Interview questions [1]

      Question 1

      How to config nat on fortinet fw
      Answer question
      Negative experience
      Difficult interview

      Application

      I applied online. I interviewed at NTT DATA (Bad Homburg v. d. Höhe) in Aug 2017

      Interview

      I was asked to come for an interview for the role as a network security engineer but they asked me if I could see myself doing Network Routing and Switching, just a side note , if someone with 10+ years of experience comes over for an interview and worked for the biggest companies in the world, dont treat them like they are little kids.

      Network Security Engineer Interview

      May 24, 2012
      Anonymous Interview Candidate
      Bengaluru
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 1 day. I interviewed at NTT DATA (Bengaluru) in Mar 2012

      Interview

      The interviews are the best at dimension data although when the candidate is being driven through 3 gruesome rounds and after selection, they get the crazy adrenaline of confusion to send the offer letter and almost become invisible when asked for response, especially with the interviewer Manoj. This is mostly because of the availability of the candidates. Please attend the interviews only if you don't have other companies in the radar.

      Interview questions [1]

      Question 1

      Describe the packet flow of ASA between 2 different sites via L2L VPN with nat control enabled?
