  • Escalate unresolved or high‑impact issues to senior support engineers following standard procedures.
  • Maintain detailed incident records, solutions and knowledge‑base articles for future reference.
  • Follow ITIL‑based processes and information‑security guidelines to ensure compliance.
  • Participate in night‑shift rotations to support users across the USA and other time zones.
  • Continuously update personal knowledge of emerging tools, technologies and best practices.
  • Collaborate with cross‑functional teams to improve service delivery and customer satisfaction.
  • Contribute to team meetings, share insights and suggest process improvements.

Technical questions 5
Explain OOP (Object-Oriented Programming) principles with real-world examples in Windows Os. Answer
Model answer: 1. Encapsulation (data hiding via private fields/getters). 2. Abstraction (hiding implementation complexity). 3. Inheritance (code reusability). 4. Polymorphism (method overriding/overloading).
What is the time and space complexity of QuickSort vs MergeSort? Answer
Model answer: QuickSort: Average O(N log N) time, O(log N) space. Worst O(N^2). MergeSort: Guaranteed O(N log N) time, but requires O(N) auxiliary space.
Explain the difference between SQL Indexing (B-Tree vs Hash) and when not to use an index. Answer
Model answer: Indexes speed up SELECT queries via B-Trees. However, they slow down INSERT, UPDATE, and DELETE operations because indexes must be updated on disk. Avoid on low-cardinality columns (e.g., boolean flags).
What happens under the hood when you enter a URL in a browser? Answer
Model answer: 1. DNS lookup (resolves IP). 2. TCP 3-way handshake (SYN, SYN-ACK, ACK). 3. TLS negotiation for HTTPS. 4. HTTP GET request sent. 5. Server responds with HTML/CSS/JS. 6. Browser renders DOM & CSSOM tree.
What is the difference between REST and GraphQL APIs? Answer
Model answer: REST uses multiple fixed endpoints with possible over/under-fetching. GraphQL uses a single endpoint allowing clients to query exact fields in a single request.
Behavioural & HR questions 3
Why do you want to join Guidehouse as a Junior Service Desk Engineer?
Highlight Guidehouse's market reputation, recent tech innovations, and how your skills in Windows Os directly solve their team's objectives.
Describe a challenging bug or academic project roadblock and how you resolved it.
Use the STAR method: Situation (project context), Task (what needed solving), Action (specific tools/logic applied), Result (quantifiable positive outcome).
How do you handle strict deadlines or sudden scope changes?
Explain your prioritization strategy, proactive communication with mentors/peers, and agile mindset.
