Hitachi Energy is a global leader in electrification, delivering mission‑critical power solutions to more than 140 countries. With a heritage of over a century of innovation, the company combines the engineering excellence of Hitachi with the energy expertise of former ABB Power Grids. Headquartered in Switzerland, Hitachi Energy employs over 56,000 professionals and generates roughly $20 billion in revenue, focusing on sustainable, reliable, and affordable power for the next generation. The organization’s core values—safety, integrity, and collaboration—drive a culture where engineers are encouraged to push technological boundaries while caring for colleagues and the planet. The role of Associate Project Engineer – Cyber Security is positioned within the Mission Critical Telecommunication Solutions (MCS) team. The incumbent will support global HVDC projects by adapting cyber‑security measures for SCADA and HMI environments, designing secure network architectures, and ensuring compliance with industry standards. This is a hands‑on technical position that bridges pre‑sales, product development, and field implementation, offering fresh graduates a fast‑track exposure to high‑impact energy infrastructure. Key Responsibilities: 1. Adapt HVDC cyber‑security solutions for SCADA & HMI and develop functional architecture documents. 2. Create and execute test‑case scenarios, participate in Factory Site Tests (FST), and troubleshoot security‑related issues. 3. Design secure network topologies for SCADA systems, incorporating advanced firewalls, VPNs, and intrusion detection/prevention systems. 4. Evaluate and harden all external connections to the SCADA network, applying vendor‑provided security features. 5. Monitor third‑party security patches, manage patch deployment, and ensure system reliability. 6. Implement controls for any back‑door access points and deploy internal/external IDS/IPS solutions. 7. Conduct technical audits of SCADA devices, networks, and connected assets to identify vulnerabilities. 8. Perform physical security surveys of remote sites, assess risks, and recommend mitigation measures. 9. Maintain test environments with up‑to‑date hardware/software, manage server/workstation backups, and oversee image handling. 10. Ensure adherence to external regulations (IEC, IEEE) and internal security policies. Tech Stack & Tools: SCADA platforms (e.g., IEC 61850, DNP3), networking protocols (TCP/IP, VPN, VLAN), security tools (firewalls, IDS/IPS, anti‑virus), scripting (Python/Bash), basic C/C++ knowledge, MS Office suite, and familiarity with IEC/IEEE standards. Growth Path: Starting as an Associate Project Engineer, high performers can progress to Senior Project Engineer, Lead Cyber‑Security Architect, or Product Manager for HVDC solutions, with opportunities to work on global projects and cross‑functional teams. Why Join Hitachi Energy? The company offers exposure to cutting‑edge energy infrastructure, a collaborative multicultural environment, and a clear commitment to sustainability. Fresh graduates gain mentorship from seasoned engineers, access to world‑class training programs, and the chance to contribute to projects that power entire nations.

What is the difference between WHERE and HAVING clauses in SQL? Answer ▼
Model Answer: WHERE filters rows before any groupings are applied, while HAVING filters aggregated groups after GROUP BY has executed.
Explain SQL Window functions: ROW_NUMBER(), RANK(), and DENSE_RANK(). Answer ▼
Model Answer: ROW_NUMBER() assigns unique sequential integers. RANK() assigns identical ranks to ties and skips ranks. DENSE_RANK() assigns identical ranks to ties without skipping rank numbers.
How do you handle NULL and missing values during data cleaning in Python/Pandas? Answer ▼
Model Answer: Use .isna().sum() to identify missing values. Impute with mean/median using .fillna() or remove with .dropna(subset=[...]) depending on variance impact.
What is the difference between Star Schema and Snowflake Schema in Data Warehousing? Answer ▼
Model Answer: Star Schema has denormalized dimension tables directly connected to the central Fact table. Snowflake Schema normalizes dimension tables into sub-dimensions to minimize redundancy.
How do you calculate MoM (Month-over-Month) growth in SQL? Answer ▼
Model Answer: Use LAG(revenue, 1) OVER (ORDER BY month) to fetch the previous month's revenue and compute (revenue - prev_revenue) / prev_revenue * 100.
