Preparation Guide for the Position of Network Engineer – NOC at Galaxy Net
1. Understand the Role and Requirements
• Study the job description thoroughly. The core duties involve configuring Juniper, MikroTik, and various Cisco‑style switches, monitoring OLT platforms, and handling access points and home routers.
• Note the required experience: 2‑5 years in IT‑enabled services or ISP environments, with at least a diploma or bachelor’s degree.
• Required certifications (preferred but not mandatory): JONCIA, CCNA, MTCNA, MTCRE.
• The role is full‑time, office‑based in Dhaka (Aftabnagar).
2. Technical Skill Development
a. Router and Switch Configuration
– Juniper: Review Junos OS basics, routing protocols (OSPF, BGP), and CLI commands. Use the Juniper vLabs free lab environment to practice.
– MikroTik: Study RouterOS, wireless CAPsMAN, firewall/NAT rules, and L2TP/IPsec tunnelling. Follow the MikroTik Certified Network Associate (MTCNA) syllabus.
– Cisco/Broadcom/BDCOM/Huawei switches: Refresh VLAN, STP, VTP, port‑security, and QoS configurations. Set up a GNS3 or Cisco Packet Tracer lab with mixed vendor images.
b. OLT Platforms
– Identify the specific OLT models listed (BDCOM, VSOL, Huawei, TBS, C‑Data, ECOM, Aurora). Download vendor manuals and configuration guides.
– Practice EPON/GPON provisioning, creating service profiles, and managing ONU/ONT devices. Many vendors provide demo firmware that can be run in a virtual environment.
c. Access Points and Home Routers
– Familiarize yourself with common AP brands (Ubiquiti, TP‑Link, Huawei). Study SSID broadcasting, WPA3 security, captive portal setup, and seamless roaming.
– For home routers, review typical ISP provisioning steps, DHCP relay, and remote management via TR‑069.
d. Core Networking Protocols
– Deepen knowledge of IPv4/IPv6, routing (static, OSPF, BGP, RIP), switching (VLAN, QinQ, MSTP), and tunneling (GRE, IPsec, L2TP).
– Understand network monitoring tools (SNMP, NetFlow, sFlow, Syslog) and NOC‑specific platforms (SolarWinds, PRTG, Zabbix).
e. Customer Relations & IT Support
– Review best practices for ticket handling, SLA adherence, and effective communication with non‑technical clients.
– Practice troubleshooting steps: symptom identification → isolation → root‑cause analysis → resolution documentation.
3. Certification Path (if not already held)
• CCNA – Cisco’s official curriculum covers routing, switching, network security, and basic automation. Prepare with the Cisco Learning Network and lab practice.
• MTCNA – MikroTik’s entry‑level certification. Use the MikroTik Academy resources and complete hands‑on labs on RouterOS.
• JONCIA – Juniper’s Associate certification. Study the Juniper Learning portal, focus on Junos OS fundamentals and routing protocols.
Aim to obtain at least one of these before the interview to strengthen your profile.
4. Build a Targeted Resume
• Header: Full name, contact number, professional email, and location (Dhaka).
• Objective: One concise sentence stating your goal to contribute as a NOC Network Engineer at Galaxy Net, highlighting 3+ years ISP experience.
• Technical Skills Section: List each vendor and technology exactly as in the job posting – Juniper (basic), MikroTik, BDCOM, Cisco, Huawei, OLT platforms, APs, Home Routers, SNMP, NetFlow, etc.
• Certifications: CCNA, MTCNA, JONCIA, etc., with dates.
• Professional Experience: For each role, use bullet points (plain text) that quantify achievements (e.g., “Managed 200+ customer circuits with 99.9 % uptime”, “Reduced mean time to repair by 15 % through proactive monitoring”).
• Education: Diploma/Bachelor details.
• Additional: Mention familiarity with ticketing tools (ServiceNow, OTRS), scripting (Python/Bash) for routine tasks.
5. Practical Interview Preparation
a. Technical Questions
– Be ready to explain how to configure a basic OSPF area on a Cisco switch and a Juniper router.
– Prepare to discuss the steps for provisioning a new ONU on a BDCOM OLT.
– Expect scenario‑based troubleshooting: “User cannot ping the internet, but can ping the gateway – what do you check?”
b. Hands‑On Demonstrations
– Some interviewers may ask you to configure a VLAN and a trunk on a Cisco switch using a laptop. Have a lab ready (real hardware or virtual).
– Prepare a quick configuration script for MikroTik firewall NAT.
c. Behavioral Assessment
– Highlight experiences handling high‑volume tickets, meeting SLA targets, and communicating with customers under pressure.
– Use the STAR method (Situation, Task, Action, Result) to structure answers.
d. Company Knowledge
– Review Galaxy Net’s website (https://galaxynetbd.com/). Note their service portfolio, recent news, and network footprint in Bangladesh.
– Understand the local ISP market, typical challenges (e.g., last‑mile connectivity, bandwidth management), and be prepared to suggest improvements.
6. Soft Skills and Personal Preparation
• Ensure you meet the age requirement (22 +).
• Dress in business‑formal attire for the office interview.
• Bring copies of your updated CV, certification PDFs, and a list of references.
• Prepare a short “elevator pitch” summarizing your background, key achievements, and why you fit the Galaxy Net culture.
7. Application Submission

• After submitting, send a polite follow‑up email to the HR contact (if an address is provided) within 3‑4 days, reaffirming your interest and attaching the same documents.
8. Post‑Application Follow‑Up
• Mark the application deadline (January 7 2026) on your calendar.
• If you do not hear back within two weeks, consider a brief phone call to the HR department to confirm receipt.
• Continue preparing for possible technical tests while waiting for a response.
9. Salary Negotiation (if an offer is extended)
• Research typical NOC Engineer salaries in Dhaka (range: Tk. 20,000‑30,000).
• Highlight your certifications and any cost‑saving projects you delivered in previous roles.
• Be ready to discuss the performance bonus, mobile bill reimbursement, and festival bonuses mentioned in the posting.
10. Final Checklist
